How to Crochet a Mini Mushroom Keychain – Step-by-Step Pattern

If you’ve been scrolling through craft fairs, Etsy shops, or Instagram feeds lately, you’ve probably noticed the explosion of adorable amigurumi keychains dangling from backpacks and purses everywhere. Among the most beloved of these tiny treasures is the mini mushroom keychain — a charming little toadstool that’s equal parts whimsical and wearable. The good news? You don’t need to be an advanced crocheter to make one. This step-by-step pattern is beginner-friendly, works up quickly, and produces results that look like they came straight from a boutique shop.

Whether you’re new to amigurumi or just looking for a fast and satisfying project to use up yarn scraps, this tutorial will walk you through every stitch, every round, and every finishing detail so your mushroom keychain turns out perfectly — every single time.

What Is Amigurumi and Why Mushrooms?

Amigurumi is the Japanese art of knitting or crocheting small stuffed animals and characters. The word itself comes from “ami,” meaning knitted or crocheted, and “nuigurumi,” meaning stuffed doll. While the technique originated in Japan, it has taken the global crafting world by storm because the projects are compact, inexpensive, and incredibly satisfying to finish.

Mushrooms hold a special place in the amigurumi world. They’re a simple, iconic shape — a rounded cap sitting on top of a stout little stem — which makes them perfect for beginners who want to try the craft without committing to a complex pattern. They’re also endlessly customizable. You can make spotted toadstools, pastel fairy mushrooms, or even spooky dark-capped versions for Halloween. Once you understand this base pattern, you’ll be able to adapt it to suit any color palette or aesthetic you love.

Materials You’ll Need

Before you pick up your hook, gather everything you need so the process flows smoothly from start to finish.

Yarn: You’ll need two colors — one for the mushroom cap and one for the stem. Worsted weight yarn (size 4) works well for a keychain that’s about two to two and a half inches tall. For a tinier version, you can use fingering weight or sport weight yarn with a smaller hook. Acrylic yarn is ideal because it holds its shape, is easy to wash, and comes in a rainbow of colors. Red and white is the classic toadstool combination, but don’t let that limit you.

Crochet Hook: A 3.5mm hook is a great match for worsted weight yarn when making amigurumi, because working slightly tighter than the yarn label suggests helps close up gaps so the stuffing doesn’t show through. If you’re using thinner yarn, drop down to a 2.5mm or 2.75mm hook.

Safety Eyes: Two 6mm black safety eyes give your mushroom a cute, polished look. If you’re making this keychain as a gift for a child under three years old, embroider the eyes with black yarn instead, as safety eyes pose a choking hazard for very young children.

Polyester Fiberfill: A small pinch is all you need for each piece. Having a toothpick or the eraser end of a pencil on hand makes it easier to push stuffing into small spaces.

White Felt or White Yarn: For the spots on the cap. You can either cut tiny circles from white felt and glue them on with fabric glue, or embroider small circles using a yarn needle and white yarn.

Keychain Ring and Jump Ring: These are available at any craft store or online. A lobster clasp keychain ring with a jump ring loop works best because it allows the mushroom to swing freely.

Yarn Needle: For weaving in ends and sewing the pieces together.

Scissors: A small, sharp pair works best for clean cuts near finished pieces.

Stitch Marker: Helpful for keeping track of the beginning of each round when working in a continuous spiral, which is standard for amigurumi.

Pins: Straight pins help you position pieces before sewing them together permanently.

Gauge

Gauge isn’t critical for this project since we’re making a stuffed toy rather than a garment. However, as a rough reference, with worsted weight yarn and a 3.5mm hook, the finished mushroom cap should be approximately 1.75 to 2 inches in diameter, and the stem should be about 1 inch tall.

Pattern: Mushroom Cap

The cap is worked from the top down in a continuous spiral. Place a stitch marker at the beginning of each round and move it up as you go.

With cap color yarn:

Round 1: Start with a magic ring, work 6 sc into the ring. Pull the ring closed. (6)

Round 2: Inc in each st around. (12)

Round 3: Sc 1, inc repeat around. (18)

Round 4: Sc 2, inc repeat around. (24)

Round 5: Sc 3, inc repeat around. (30)

Round 6: Sc 4, inc repeat around. (36)

Round 7: Sc in each st around. (36)

Round 8: Sc in each st around. (36)

Round 9: Sc 4, dec repeat around. (30)

Round 10: Sc 3, dec repeat around. (24)

Round 11: Sc 2, dec repeat around. (18)

At this point, insert your safety eyes between rounds 5 and 6, spaced about 6 stitches apart. This is the front of your mushroom cap. Once the eyes are in, secure the washers on the inside before continuing.

Round 12: Sc 1, dec repeat around. (12)

Before completing Round 13, stuff the cap firmly with fiberfill. Use enough that the shape holds up nicely but not so much that it stretches the stitches.

Round 13: Dec around. (6)

Fasten off, leaving a short tail. Use your yarn needle to weave through the remaining 6 stitches and pull tight to close the opening. Weave in the end. Set the cap aside.

Pattern: Mushroom Stem

The stem is worked from the bottom up in a continuous spiral.

With stem color yarn:

Round 1: Start with a magic ring, work 6 sc into the ring. Pull the ring closed. (6)

Round 2: Inc in each st around. (12)

Round 3: Sc 1, inc repeat around. (18)

Round 4: Working in BLO, sc in each st around. (18) — This creates a small ridge that acts as the bottom rim of the stem, giving it a flat, stable base.

Rounds 5–9: Sc in each st around, working through both loops as usual. (18) — Repeat this for 5 rounds total.

Round 10: Sc 1, dec repeat around. (12)

Round 11: Sc 1, dec repeat around. (8)

Before closing, stuff the stem lightly with fiberfill. You want it firm enough to hold its shape but not so stuffed that it becomes a hard lump.

Do not fasten off yet. Leave a long tail of about 12 to 15 inches for sewing the stem to the cap.

Attaching the Stem to the Cap

This is the step that transforms two separate pieces into one cohesive little mushroom, so take your time here.

Position the open top of the stem against the underside of the cap, centering it as best you can. The inside of the cap has a natural indent from the stuffing, and the top of the stem should nestle right into it. Use pins to hold the pieces in place while you sew.

Thread the long tail from the stem onto your yarn needle. Working around the entire opening, whipstitch or mattress stitch the two pieces together, catching the edge stitches of both the stem and the cap underside with each pass of the needle. Pull each stitch firmly so the connection is secure, but don’t pull so tight that the fabric puckers.

Once you’ve gone all the way around, run the needle through the inside of the mushroom body a couple of times to anchor the yarn, then trim the end close. If you feel the join is slightly loose anywhere, go around a second time before fastening off.

Adding the Spots

The polka dot spots are what make this mushroom look instantly recognizable and adorable, so don’t skip this step even if you’re in a hurry.

Felt spots: Cut small circles from white felt. The easiest way to get consistent circles is to use a hole punch — a standard ¼-inch punch makes perfectly sized spots. Arrange them on the cap in a pattern you like (usually three spots looks balanced for a cap this size), then glue them down with a small dab of fabric glue or a tiny stitch at the center of each circle with white thread.

Embroidered spots: If you prefer not to use felt, thread a yarn needle with a length of white yarn. Work small circular satin stitches on the cap, bringing the needle up through the center of where you want each spot, then working small straight stitches radiating outward from that center point to build up a filled circle. Alternatively, work a French knot or a small cluster of chain stitches for a slightly different texture.

Adding the Keychain Loop

The keychain attachment is what elevates this from a cute little toy to something you can actually carry around with you every day.

Cut a length of yarn about 8 inches long and fold it in half. Insert your crochet hook through the top of the mushroom cap (at the very top center, through the gathered stitches where you closed round 13) and draw the folded loop partway through so you have a small loop sticking out of the top. Pass the two tail ends through this loop and pull snug to form a lark’s head knot. You should now have two strands of yarn coming out of the top of the mushroom.

Thread both strands through a jump ring, then tie them together tightly with a double or triple knot. Trim the ends close to the knot. Attach your keychain ring to the jump ring, and your mushroom is ready to use.

Alternatively, you can crochet a small chain of 10 to 12 stitches and use that as your loop instead of yarn strands, working it into the top of the cap and joining the ends to the jump ring. This gives a slightly more polished, finished look.

Tips for the Best Results

Working amigurumi well is partly about understanding a few habits and techniques that experienced makers use almost instinctively. Here are the ones that will make the biggest difference for this project.

The magic ring is worth learning properly because it eliminates the gap you sometimes get when starting with a chain-two and working into the first chain. If the magic ring frustrates you at first, search for a video tutorial specifically on this technique — seeing someone’s hands work through it usually makes it click immediately.

Tension is everything in amigurumi. If your stitches are too loose, the stuffing peeks through and the finished piece looks sloppy. If they’re too tight, it becomes difficult to insert your hook and your hands tire quickly. Aim for a fabric that feels dense and firm but that your hook still moves through comfortably.

Working in a continuous spiral rather than joining each round with a slip stitch is the standard for amigurumi. The slight jog this creates at the beginning of each round becomes invisible once the piece is stuffed and finished.

Always close the magic ring tightly before beginning round two. A loose center looks unprofessional and can unravel over time with use.

If your cap comes out slightly asymmetrical, block it gently by lightly misting it with water and reshaping it with your hands, then leaving it to dry on a flat surface.

Customization Ideas

Once you’ve made the basic pattern a couple of times, you’ll find yourself wanting to riff on it in every direction. Here are some variations to try.

For a pastel version, use soft lavender or dusty rose for the cap with a cream stem — perfect for spring markets or as a gift for someone who loves cottagecore aesthetics. Add tiny embroidered flowers on the cap instead of spots for extra charm.

For a spooky Halloween mushroom, use deep plum or black for the cap with an orange stem. Skip the white spots and add a small crocheted spider or tiny embroidered lightning bolt instead.

For a set of keychains in different sizes, try the same pattern at three different yarn weights — fingering, DK, and worsted — to create a family of mushrooms in ascending sizes. These make an especially sweet gift tied together with a ribbon.

For a glow-in-the-dark version, use glow-in-the-dark yarn (yes, it exists!) for the cap or the spots. These are genuinely exciting to discover in a dark bag when you’re searching for your keys.

You can also skip the keychain hardware entirely and sew a small loop of ribbon to the top to use as a bag charm, zipper pull, or Christmas ornament.

Caring for Your Mushroom Keychain

Since keychains take daily wear and tear, it’s good to know how to keep yours looking fresh. If you used acrylic yarn, you can gently hand wash the mushroom with cool water and a drop of mild soap, then press out excess water between two clean towels and reshape it to dry flat. Never wring it out or run it through a dryer on high heat, as this can distort the shape. Avoid exposing it to prolonged direct sunlight if you used any highly saturated colors, as this can cause fading over time.

If the felt spots start to lift at the edges after washing, a fresh dot of fabric glue pressed down firmly and left to dry overnight will restore them.

Final Thoughts

A mini mushroom keychain is one of those projects that earns its place in a crocheter’s regular rotation — not just because it’s quick and satisfying, but because it makes a genuinely lovely gift for friends, family, or anyone you want to charm with something small and handmade. The skills you practice here — the magic ring, working in the round, increasing and decreasing to shape a three-dimensional form, and seaming pieces together — are the same foundational skills that will carry you into more complex amigurumi patterns as your confidence grows.

So gather your yarn scraps, pour yourself something warm to drink, and settle in for a couple of hours of happy crocheting. Your tiny toadstool is waiting to be made.
