I started glass painting a couple years ago and it has become one of my favorite ways to relax in the evenings.
Lately I have been trying out characters from Demon Slayer on some old glass jars and plates.
Tanjiro and Giyu both have strong looks that translate nicely to this kind of project.
I put together these ideas based on what worked for me when I tested them out.
Some turned out better than others but they all felt worth sharing.
Chibi Tanjiro and Giyu on a Clear Storage Jar

Painting a wide-mouth glass jar with chibi Tanjiro and Giyu turns an ordinary container into a display piece that shows off both characters side by side. The jar’s round, transparent surface lets the painted figures wrap around the curve without blocking light, while the blue water splashes add motion between the two designs. Brown and teal clothing colors stand out sharply against the clear glass, and the small scale keeps the details readable even when the jar sits on a shelf or counter.
What makes this idea useful is that the jar shape works equally well as a utensil holder, pencil cup, or small plant container once the paint dries. The same two-character layout can be simplified by dropping the water effects or swapped onto a shorter drinking glass if a taller jar feels too big. For table styling, the transparent background lets the painted figures catch light from any angle without needing extra backing. The motif adapts easily to other Demon Slayer pairings by changing only the hair and haori colors on the same jar size.
Dual Character Wine Glass with Matching Background Motifs

A wine glass painted with Tanjiro on one side and Giyu on the other creates a compact fan project that uses the glass curve to display two characters at once. Tanjiro’s green checkered haori and red hair sit opposite Giyu’s dark hair and swirling blue water details, with the transparent surface letting both designs show through without overlapping. The stem keeps the painted section elevated so the base stays clear for handling. This fits the wine glass category and works as a display piece or small gift.
What makes this idea useful is how the rounded bowl naturally separates the two characters while the water and checkered motifs fill the space without extra outlines. You could scale the same split layout down to a drinking glass or stretch it taller on a glass vase by lengthening the water lines. For shelf styling, this kind of painted glass catches light through the clear areas and stands out next to plain drinkware. The design could be reworked into a single character version or simplified by keeping only the faces and main color blocks for a faster project.
Stacked Tanjiro and Giyu on a Green Glass Bottle

A tall green glass bottle works well for this Demon Slayer project because the curved surface gives room to place two characters vertically. Tanjiro fills the upper half with his red hair and sword raised, while Giyu sits below in his dark uniform and patterned haori. Blue and white water splashes run across both sections to link the figures and match their breathing styles. The transparent glass lets light pass through the thinner paint areas, making the water details stand out.
What makes this idea useful is how the bottle shape naturally supports a two-character layout without needing extra space. You could reuse the water wave pattern on a shorter jar or a clear vase if you want less height. For shelf styling, this type of painted bottle fits near a window or lamp where the green glass picks up light. The same vertical split could be simplified by painting only one character or swapped for other pairs from the series.
Tall Vase with Split Tanjiro and Giyu Portraits

A tall cylindrical glass vase works well for this vertical split layout. One half carries Tanjiro’s green and black checkered haori pattern with his head and shoulders centered on it, while the other half shows Giyu’s blue background and yellow-green diamond haori with his portrait placed beside it. Gold dots run along the top and bottom rims to frame the design. The clear glass lets the painted sections stand out sharply without extra backing.
What makes this idea useful is the tall shape that gives each character enough vertical space without crowding. The same split approach adapts easily to a shorter jar or wide bottle if you want a smaller piece for a shelf. The bold block patterns from the show stay recognizable even when simplified, so the vase reads clearly as fan decor. For table styling, this kind of painted glass adds height and color without needing extra objects around it.
Candle Holder with Tanjiro and Giyu Profiles and Wisteria Border

A round glass candle holder painted on the outside with Tanjiro and Giyu sitting back to back makes a strong base for this project. The design uses side profiles, dark clothing details, and hanging purple wisteria on both sides, with a water line at the bottom to ground the scene. Translucent paint allows the candle flame inside to light up the figures and background evenly around the curve.
What makes this idea useful is how the cylinder shape spreads the light without extra tools. The same character placement and vine border could move to a square jar or a shorter tumbler if you want a different scale. For table styling, the low height keeps the flame visible while the painted band adds interest from all angles. You could simplify the water and flowers to just the two profiles if you need a faster version for gifts.
Split-Design Sun Catcher with Tanjiro and Giyu

A circular glass sun catcher uses a vertical split to place Tanjiro on the left half and Giyu on the right half. The left side carries green and black checkered sections while the right side uses blue and gold geometric shapes, both separated by a clean black line and surrounded by matching border patterns. A small metal ring at the top makes the piece easy to hang, and the translucent painted sections let light pass through when placed near a window.
What makes this idea useful is how the bold outlines and contrasting background patterns keep the two characters readable even at small scale. The round shape works well for hanging in a single window pane or grouping several together on a larger glass surface. You could rework the same split layout onto a glass ornament, a small glass plate, or a set of coasters by keeping the checkered and geometric fills but changing the character expressions. The design stands out on Pinterest because the two-color background treatment makes the split instantly clear without extra detail work.
Round Glass Coasters with Tanjiro and Giyu Portraits

Round glass coasters work well for this type of project because the circular shape naturally frames close-up character portraits. The transparent surface lets the watercolor-style paint show through with soft color blends and visible brush texture, while the bust views of Tanjiro and Giyu stay centered without needing extra background elements. Painting directly on the glass keeps the images clear and allows light to pass through the thinner areas of color.
What makes this idea useful is how simple it is to adapt the same portraits onto other small round glass items like ornaments or jar lids. The set format works especially well for table use or as quick gifts, and the motif could be reduced to just the head and shoulders if you want to finish more pieces faster. For shelf styling, these coasters add a clear anime detail without taking up much space.
Split-Design Drinking Glass Featuring Tanjiro and Giyu

A tall drinking glass can carry two characters side by side by splitting the surface vertically. One half uses green paint for Tanjiro in his checkered haori with curved strokes around him, while the other half uses blue for Giyu with wave shapes filling the space. The clear glass keeps the painted areas from blocking all light, so the design stays visible from multiple angles without looking solid. This layout works as a drinking glass project because the cylinder shape gives enough flat space for full-body silhouettes without crowding.
What makes this idea useful is that the vertical split keeps the two color schemes clean and easy to copy on any tall glass you already have. You could shrink the same layout onto a shorter tumbler or reuse the wave and swirl motifs on a glass vase for a shelf display. The strong color contrast makes the finished piece stand out in photos, which helps if you want to share it online. For a gift, the same split approach works on a clear bottle or jar by adjusting the height of the painted sections to fit the new shape.
Wave-Swept Glass Bowl with Tanjiro and Giyu

A clear glass bowl serves as the base for this Demon Slayer project, with the curved surface allowing blue wave patterns to flow around both characters. Tanjiro appears on one side in his checkered uniform, and Giyu on the other in his haori, each set inside swirling water lines that follow the bowl’s round shape. The transparent glass keeps the design from feeling heavy while letting light highlight the white foam details against the blue waves.
What makes this idea useful is how the bowl’s curve turns two separate characters into one connected scene that shifts as you walk around the table. You could scale the same wave layout down for a smaller mixing bowl or stretch it taller onto a vase by keeping the water lines continuous around the form. For everyday use, this painted glass works as a fruit bowl or centerpiece without blocking light, and the wave motif could transfer to plain drinking glasses if you drop the full figures and repeat just the foam lines instead.
Fox Mask Storage Jar

A clear mason jar turns into a Demon Slayer themed pencil or brush holder when covered with repeating fox mask faces and blue hexagonal crests. The masks use red and white paint with simple line details, while the crests show a white flower motif on a dark blue field with gold trim. These elements sit at mid-jar height so the clear glass above and below stays open for light and visibility. The approach works well for any cylindrical glass jar meant to hold desk tools or small items on a shelf.
What makes this idea useful is the even spacing of the small motifs, which keeps the jar functional while adding pattern. You can scale the same fox mask and crest down for spice jars or up for a larger vase by changing how many repeats fit around the curve. For table styling, this kind of painted glass fits a craft desk or anime collection without needing extra lighting. The design also moves easily to plain drinking glasses if you want a matching set.
Tanjiro and Giyu Profiles on a Glass Candle Holder

A short, round glass candle holder gets painted with side profiles of Tanjiro and Giyu placed on opposite sides. Tanjiro appears in green and black checkered fabric with his sword earring visible, while Giyu shows in his blue patterned jacket and long hair. The clear glass lets the candle flame illuminate the unpainted sections and make the painted areas stand out through simple color blocking and line work. This approach works as a candle holder project where the light source becomes part of the finished piece.
What makes this idea useful is how the cylinder shape lets you see one character or both depending on where you place it. You could repeat the same opposing profiles on a drinking glass or small vase by keeping the same solid color areas and minimal detail. For table styling, this kind of painted glass works well as a nightstand light or small accent that needs no extra base. The design stays simple enough to copy onto any clear jar you already have.
Stained Glass Style Square Coasters with Tanjiro and Giyu

Square glass coasters painted to look like stained glass panels offer a simple way to feature Tanjiro and Giyu. Each coaster uses black outlines to divide sections of color, creating a circular frame around the character with wave motifs and flower accents added around the edges. The clear glass base lets light move through the painted areas, which helps the colors stand out without needing extra backing. This approach fits the glass coaster or small panel category and works best when the design stays contained within the square shape.
What makes this idea useful is how the square format keeps the project compact and easy to display on a table or shelf. The same stained glass layout can be scaled down for round coasters or copied onto a larger glass tray if you want more surface area. For gifts, these coasters give a clear Demon Slayer theme while staying functional as drink rests. The strong color blocks and character placement also make the finished pieces photograph well for sharing.
Tanjiro and Giyu Portraits on Round Glass Beads

Small glass beads painted with Demon Slayer character portraits turn the curved surface into a canvas that wraps the design around the entire object. The transparent glass lets light pass through the unpainted areas while the painted sections with wave patterns, clouds, and metallic gold accents stay opaque and reflective. This approach works as a compact glass ornament or giftable decor piece that can sit on a shelf or be strung for display.
What makes this idea useful is the small scale, which lets you test detailed portraits without committing to a large surface. The bead shape adapts easily to other round glass items like clear marbles or larger spheres if you want a different size. For table styling, a few of these beads grouped in a shallow dish create a focused accent without taking much space. The same portrait and background layout could be simplified to just the face on a flat glass pendant if the full wraparound design feels too involved.
Giyu Water Breathing Wave Glass Panel

A rectangular glass panel with a metal frame lets you paint bold blue and white waves along one edge to capture the flowing motion of a water breathing motif. The clear center keeps the design light while the painted waves use thick brush strokes and small dots for spray effects that stand out on the transparent surface. A geometric pattern in yellow, green, and red fills the opposite edge as a structured border that balances the movement on the other side. This glass panel approach works as window decor or a flat display piece where the transparency of the glass highlights the contrast between the painted sections and the open middle.
What makes this idea useful is the split layout that keeps most of the glass clear so light still passes through. You could scale the wave pattern down to fit a glass bottle or a small ornament if you want something that hangs in a window. The geometric border can be simplified to just two colors or swapped for a different repeating shape when you try the same idea on a glass plate or tray. For a gift, something like this stays flat and easy to wrap while still showing a clear Demon Slayer reference through the water motif.
Split Theme Bottle Featuring Giyu and Tanjiro

A tall clear glass bottle works well for this project because the large curved surface lets you divide the design into two distinct halves. The upper section shows Giyu with swirling blue water motifs while the lower section shows Tanjiro surrounded by red and orange flame patterns. The transparent glass keeps the colors bright and allows the painted areas to stand out clearly without needing an opaque background. This approach fits the glass bottle category and gives enough space for full character portraits plus surrounding elements.
What makes this idea useful is the vertical split that pairs two characters on one object without crowding. The same layout could be simplified by using fewer waves or flames if you want to finish faster or scaled down onto a smaller bottle. A piece like this works especially well as shelf decor or a gift because the bottle shape is easy to move around and the bold color blocks stay visible from a distance. You could rework the idea onto a vase or jar by keeping the same top-and-bottom division but swapping in different motifs.
Faux Stained Glass Lantern with Tanjiro and Giyu Panels

A cylindrical metal lantern holds several flat glass panels painted in a faux stained glass style that divides each section with black leading lines. The panels show side profile portraits of Tanjiro with his checkered haori and red hair alongside Giyu with his dark hair and wave-patterned haori, set against colored backgrounds that include flowers and geometric shapes. Translucent paint allows light from inside the lantern to pass through the glass and project the design onto the surface below. This creates a compact display piece that works as both a light source and a character showcase.
The cylindrical shape lets viewers see multiple characters simply by turning the lantern, which makes it easy to adapt for smaller glass jars or taller vases using the same panel layout. You could swap the wave and flower motifs for other simple repeating patterns if you want to feature only one character per section. This type of project stands out for gifting because the painted glass produces colored light patterns that change with the time of day. The small scale also makes it simple to try first on individual glass tiles before committing to a full frame.
Tanjiro and Giyu Portraits on a Clear Glass Orb

A round clear glass orb makes a strong base for this project since the curved surface lets you position two characters side by side while keeping the design visible from multiple angles. Tanjiro appears in the foreground with his red hair and green checkered robe, while Giyu sits slightly behind in blue tones against a simple painted sky. The transparency of the glass allows light to pass through the paint layers, which helps the colors stay visible without needing heavy outlining. This style works as a compact decorative sphere rather than a flat panel or bottle.
What makes this idea useful is how the small round format can be repeated with different character pairs to create a matching set. The same portrait layout could transfer to glass paperweights, large marbles, or hanging ornaments without major changes to the composition. You could drop the background entirely if you want a quicker version, or add a simple color wash behind the figures to keep the focus on the two characters. For shelf styling, this type of painted orb fits easily into small spaces where a larger glass piece would not work.
Checkered Pattern Tumblers Featuring Tanjiro and Giyu

Paint stainless steel tumblers with repeating checkered blocks that match the characters’ color palettes, then add a small chibi-style face of Tanjiro on the green and black version and Giyu on the blue, teal, and red version. Keep the squares roughly uniform in size and align them in straight rows around the lower half of each cup so the pattern reads clearly from a distance. The high-contrast color blocks against the dark background make the design bold while the compact faces sit neatly above the pattern without crowding the space.
What makes this idea useful is how the checkered layout works on any cylindrical drinkware once you mark even rows. You can simplify it by using fewer colors or shrink the squares to fit smaller glasses or bottles for a different scale. For a gift, something like this pairs well with a matching set of two so the characters sit side by side. The strong geometric pattern photographs cleanly, which helps the project show up in search results when shared as finished drinkware.
Hanging Round Glass Plate with Tanjiro and Giyu Water Scene

A round glass plate makes a strong base for this type of full-scene painting because the circular shape supports a continuous swirl of water around the two characters. The transparent surface lets light move through the blue and red painted waves, which helps the motion read clearly without extra shading. Bold linework on the characters and loose brush strokes for the water keep the design balanced so it stays visible when the plate hangs.
What makes this idea useful is how the round format turns a standard Demon Slayer motif into a ready-to-hang piece for a window or wall. You could scale the same swirling border down to a glass ornament or reuse the color split on a flat glass panel if you want a faster project. The strong contrast between the dark figures and the bright water also transfers well to other circular glass items like bowls or chargers.
Split Portrait Design on a Tall Rectangular Spray Bottle

A tall rectangular glass spray bottle works well for a vertical split layout that places Tanjiro on the left half and Giyu on the right half. The design uses flowing wave patterns to connect the two sides while keeping each character in profile facing outward. The rising sun crest sits above Tanjiro and the blue flower motif sits above Giyu, both positioned near the top to balance the composition against the clear glass background.
What makes this idea useful is the narrow bottle shape that naturally frames two characters without crowding. The same split approach could be scaled down to a smaller perfume bottle or moved to a flat-sided drinking glass while keeping the wave lines running across the center seam. For table styling or shelf display, the clear glass and gold pump already provide a finished look, so the painted section becomes the only decoration needed.
Wave Border Glass Bowl with Tanjiro Center Design

A clear glass bowl works as the base for this project, with blue and white waves painted in curved strokes along the interior sides to form a continuous border. The center holds a circular stained-glass style portrait of Tanjiro set against red and gold sections, using black outlines to separate the color blocks and keep the character visible from above. The transparent glass lets light pass through the thinner paint areas while the thicker wave lines stay opaque, which helps the whole design read clearly when the bowl sits on a surface.
What makes this idea useful is that the bowl shape naturally curves the wave pattern without extra effort, while the flat bottom keeps the central portrait easy to see. You could adapt the same border and circle layout onto a glass plate or a shallow dish if you want something that stacks or hangs instead. For table styling, this type of painted bowl stands out on its own as a centerpiece, and the wave motif can be scaled down or simplified by reducing the number of layers if you are working on a smaller glass piece.
Dual Character Lantern Using Metal Dividers

A round hanging lantern with metal framework divides the surface into clear sections for a split design of Tanjiro on one side and Giyu on the other. Translucent paint applied in panel sections lets light pass through the wave patterns and checkered clothing, keeping the faces visible on the curved glass. Bold outlines around the hair and earrings help the characters read clearly without crowding the small orb shape.
The glass surface does a lot of the work here by catching internal light and making the colors glow outward. You can adapt the same split layout and metal borders to a smaller glass ornament or a flat candle holder if you want a simpler starting shape. This type of project works well as a shelf accent near a lamp since the round form lets you turn it to show either character.
Tanjiro Checkered Tumblers

Drinking glasses painted with Tanjiro’s green and black checkered haori pattern use bold blocks on the lower half paired with loose watercolor washes and geometric shapes in blue, green, and yellow. The checkered sections sit against the clear glass so the pattern stays readable while the drips and angled shapes add contrast without covering the full surface. This keeps the design simple enough to finish in one session while still referencing the character’s signature look.
What makes this idea useful is how the checkered layout transfers directly to other glass shapes like mason jars or small vases by changing square size. The design works on a shelf or at a viewing table because the clear areas let light through and keep the pieces from looking heavy. You could drop the geometric shapes and keep only the checkers for a faster version or extend the pattern higher on taller glasses for a different proportion. The small scale also makes these easy to batch for gifts without needing much workspace.
Illuminated Glass Jar with Tanjiro and Giyu Landscape Scene

A clear glass storage jar works well for this project because its wide shape and smooth surface let a full wraparound scene sit evenly without distortion. The painting places Tanjiro on a path in the foreground and Giyu standing to the right, with layered mountains, clouds, a setting sun, and torii gates filling the rest of the jar. Internal lighting turns the translucent paint into a glowing effect that shows through the clouds and reflections on the glass. This type of project fits the glass jar category and turns an ordinary container into a lit display piece.
What makes this idea useful is how the jar’s height and curve let the light carry the landscape across the whole surface. You could scale the same mountain and character layout down to a smaller jar for a desk or move just the two figures onto a drinking glass. For table styling, this kind of painted glass adds a focused light source that works in low light without extra fixtures. The placement of the path and water details keeps the scene readable from multiple angles, so the same motif can be reused on other round glass objects.
Frequently Asked Questions
What supplies do I need to create glass paintings featuring Tanjiro and Giyu?
Start with a clean glass surface such as a jar, window panel, or vase. Gather acrylic glass paints in colors matching the characters like red for Tanjiro’s hair and checkered scarf plus blue and black for Giyu’s haori. Include fine detail brushes, a pencil for sketching, isopropyl alcohol for cleaning, and a sealant spray to protect the finished work. Optional items include stencils for outlines and a palette for mixing shades.
How do I transfer designs of Tanjiro and Giyu onto glass without errors?
Print reference images of the characters and tape them inside the glass if it is transparent. Trace the main outlines lightly with a pencil on the outside surface. For curved items like bottles, use printable transfer paper designed for glass. Work in sections to avoid smudging and keep a damp cloth nearby to correct mistakes quickly before the paint sets.
What techniques help add realistic details to Tanjiro’s scar and Giyu’s expression?
Apply base layers first and let them dry completely. Use thin layers of lighter and darker shades to build the scar texture on Tanjiro with short brush strokes. For Giyu add subtle gradients around the eyes and mouth using a dry brush technique to create depth. Practice on scrap glass first to master the flow of paint on a smooth surface.
How can I make these paintings durable for display or light use?
After the paint dries for at least 24 hours apply two thin coats of a clear acrylic sealer made for glass. Avoid placing painted items in direct sunlight or near heat sources to prevent fading. For functional pieces like coasters test a small area first and never submerge them in water unless the sealant is explicitly waterproof.
What are good ways to combine Tanjiro and Giyu in a single glass painting?
Position Tanjiro on one side facing right and Giyu on the other facing left to suggest their interactions from the series. Use a shared background element such as a misty forest or water ripples to tie the scene together. Balance the colors by echoing red accents from Tanjiro in small details on Giyu’s side for visual harmony.
