Few game worlds are as instantly recognisable as the Mushroom Kingdom — the red caps, the gold coins, the spotted toadstools, the chunky green pipes. That bright, blocky, cheerful style is a gift for crafters, because the shapes are simple, the colours are bold, and almost everything can be recreated from felt, cardboard, paper, and paint. Whether you are decorating for a Mario-themed birthday, kitting out a gaming room, or just making something fun with the kids, these projects capture the look without needing any special skills. This collection gathers five fan-inspired Mario DIY projects, each with materials and clear steps, so you can build a little slice of the Mushroom Kingdom at home.
What Does "DIY" Mean?
DIY stands for "do it yourself" — making, building, or decorating something with your own hands and everyday materials instead of buying it ready-made. It covers an enormous range, from home improvement and woodworking down to small craft projects finished at the kitchen table in an afternoon. The common thread is the choice to create rather than purchase, and the freedom to make something exactly the way you want it.
Themed crafts like these are a perfect example. Store-bought party decorations and costumes are expensive and often generic, while a handmade version can be sized, coloured, and styled precisely to your vision — and made for a fraction of the cost from supplies you may already own. Just as importantly, the making itself is part of the fun: these are projects to enjoy alongside friends or children, not just a means to an end.
Capturing the Look: Colours and Shapes
The secret to a convincing Mushroom Kingdom craft is leaning into its signature style rather than chasing fine detail. Three things carry the theme: a bold primary palette of bright red, blue, green, and gold; simple, chunky shapes like domed caps, round coins, and big circular spots; and the unmistakable pixel-block aesthetic of the classic games, where everything is built from little squares.
Keep those three ideas in mind and even a rough craft reads instantly as Mario-themed. You do not need to copy any official artwork — recreating the general colours and shapes in your own handmade style is what gives these projects their charm. For more bead, felt, and paper techniques that pair well with these builds, the wider Crafts category has plenty of related ideas.
Project 1 · Felt Hero Hat
The red cap is the most recognisable piece of the whole costume, and a felt version is quick to make and comfortable to wear. It is the centrepiece of any themed outfit and an easy win for a party.
Materials
Steps
- 1Start with a plain red cap, or sew one from red felt panels into a rounded crown with a curved brim.
- 2Cut a circle of white felt for the front emblem, large enough to sit prominently on the front.
- 3Cut a simple initial or shape from coloured felt and glue it onto the white circle.
- 4Attach the finished emblem to the front of the cap and let any glue dry fully.
Project 2 · Papier-Mache Toadstools
Oversized spotted toadstools make brilliant standing party props or room decorations. Built from a balloon and papier-mache, they are cheap, lightweight, and as large as you like — the signature shape of the Mushroom Kingdom.
Materials
Steps
- 1Inflate a balloon for the cap and stand it on a cardboard tube or rolled-card stem.
- 2Cover the cap and stem with several layers of paste-soaked newspaper strips, letting each layer dry.
- 3Once hard, pop and remove the balloon, then paint the cap a bright colour and the stem off-white.
- 4Add large white circles to the cap with paint or glued felt to finish the toadstool spots.
Project 3 · Pixel Coin & Heart Art
The pixel-block look of the classic games translates beautifully into craft form. Fuse beads or a painted grid let you build chunky coins, hearts, stars, and question blocks that make perfect gaming-room wall art or party favours.
Materials
Steps
- 1Sketch your icon — a coin, heart, star, or question block — onto graph paper, one square per pixel.
- 2For beads, lay them onto a pegboard following your grid, then fuse with an iron as directed.
- 3For a painted version, rule a grid onto canvas and fill each square as a solid block of colour.
- 4Keep edges crisp and colours flat — the blocky, low-detail look is exactly what reads as retro pixel art.
Planning a Mushroom Kingdom Party or Room
These projects shine brightest when combined into a single themed scene. For a party, think in layers: a banner sets the backdrop, papier-mache toadstools fill the floor corners, pixel-art pieces decorate the walls and tables, and felt caps turn guests into characters. Stick to that bold red-blue-green-gold palette across everything and the whole room hangs together, even with handmade, slightly imperfect pieces.
For a gaming bedroom, the same crafts become permanent decor — pixel art framed on the wall, a warp-pipe planter in the corner, a cluster of small toadstools on a shelf. Build the pieces over a few weekends rather than all at once, and lean on the bead, felt, and paper skills covered across the Crafts category to refine each one. Mixing two or three of these projects is the fastest way to a cohesive, characterful theme.
Project 4 · Warp-Pipe Planter
The green warp pipe is one of the most iconic shapes in all of gaming, and it makes a surprisingly natural planter or pen-pot. A length of wide tube, painted and capped with a rim, instantly reads as a pipe — perfect for a desk or shelf.
Materials
Steps
- 1Cut a wide tube to your chosen height for the pipe body.
- 2Add a slightly wider band or ring around the top to form the classic pipe rim.
- 3Paint the body a mid-green and the rim a brighter green, adding a darker shadow stripe down one side for depth.
- 4Drop a small plant pot or a cup of pens inside, hidden below the rim.
Project 5 · Mushroom Kingdom Banner
A themed banner is the quickest way to transform a party wall, and it is one of the most beginner-friendly projects here. A string of card flags decorated with coins, mushrooms, stars, and letters spells out a name or a message in full Mushroom Kingdom style.
Materials
Steps
- 1Cut card into matching flag shapes — squares or triangles — in the bold theme colours.
- 2Decorate each flag with a pixel coin, mushroom, star, or a single letter to spell out a name or message.
- 3Punch two holes along the top of each flag.
- 4Thread string through the holes to join the flags, then hang the finished banner across the wall.
Finishing Touches and Making It Last
A few small habits lift these crafts from good to great. Keep your colours consistent across every project — mixing or buying paint and felt in one set of reds, greens, blues, and golds means all the pieces look like they belong together. Work for crisp edges and flat colour rather than fine shading, since the bold, simple look is the whole point of the style. And for anything that will be handled or reused, a coat of clear sealant on painted pieces, or a few extra stitches on felt, keeps them sturdy for many parties to come.
Conclusion
Mario-themed crafts are some of the most rewarding fan projects you can make, precisely because the style is so simple and so joyful: bold colours, chunky shapes, and a touch of pixel charm. Start with a felt cap and a banner for a quick party setup, add papier-mache toadstools and pixel art for impact, and finish with a warp-pipe planter for the gaming room. Recreate the look in your own handmade style, keep the palette consistent, and you will build a bright, characterful slice of the Mushroom Kingdom that is far more personal — and far more fun to make — than anything off a shelf.
