  • Stitch markers
  • Polyester fiberfill stuffing
  • Tapestry needle for finishing
  • Safety eyes with washers (or embroider eyes for babies under three)

Amigurumi looks harder than it is. Almost every piece — tiny bunny, chubby cat, elephant with a felt tie — is built from the same five techniques worked over and over. Learn these five well and you can follow any amigurumi pattern in the wild.

1. The magic ring

Every amigurumi starts with a magic ring, because you need a closed center. See our 'How to Crochet in the Round' guide for the step-by-step — the version that ends with a firm tail-pull is what you want. Most patterns open with '6 sc in MR' and you're off.

2. Working in a continuous spiral

Amigurumi is NOT worked in joined rounds. You skip the slip-stitch join and spiral upward continuously — this eliminates the visible vertical seam that would ruin a smooth sphere. Use a stitch marker in the first stitch of every round to keep count.

3. Increases and the sphere formula

A basic amigurumi sphere uses the following increase pattern, starting with 6 sc in a magic ring:

  • Rnd 1: 6 sc in MR (6)
  • Rnd 2: inc in each st (12)
  • Rnd 3: *sc, inc* repeat (18)
  • Rnd 4: *2 sc, inc* repeat (24)
  • Rnd 5: *3 sc, inc* repeat (30)
  • Rnd 6: *4 sc, inc* repeat (36)
  • Rnds 7–10: sc in each st (36) — this is the straight middle section of the sphere
  • Rnd 11: *4 sc, dec* repeat (30)
  • Rnd 12: *3 sc, dec* repeat (24)
  • Rnd 13: *2 sc, dec* repeat (18) — stuff firmly now
  • Rnd 14: *sc, dec* repeat (12)
  • Rnd 15: dec around (6)
  • Fasten off, leaving a long tail. Thread through remaining stitches and pull to close.
Pattern math shortcut
For any sphere, the number of increase rounds = the number of decrease rounds. Whatever your maximum stitch count, you mirror it back down. Straight rounds in the middle set the overall size.

4. The invisible decrease

The standard 'sc2tog' leaves a visible bump. The invisible decrease is a two-second variation that hides completely:

  1. Insert hook into the FRONT loop only of the next stitch.
  2. Insert hook into the front loop only of the following stitch (both front loops now on hook).
  3. Yarn over and pull through both front loops (2 loops on hook).
  4. Yarn over and pull through both remaining loops.

Use it on every amigurumi decrease. Zero downside.

5. Stuffing and closing

Stuff in small pinches, shaping the piece with your other hand as you go. Add polyfil until the fabric feels firm but not stretched. To close the last 6 stitches: thread the tail through a tapestry needle, weave through the front loop of each remaining stitch, pull tight to cinch shut, and weave the tail into the body.

6. Assembly and seaming

For arms, legs, ears and tails, use pins to position pieces symmetrically BEFORE sewing anything. Stand back, adjust, then sew with a whip stitch or mattress stitch depending on how visible the seam will be. Assembly makes or breaks a finished amigurumi — take twice as long as you think you need.

Safety notes for babies and kids

For children under three, skip safety eyes entirely and embroider features with yarn or embroidery floss. Use polyester fiberfill (not beads) for stuffing. Cotton yarn is machine washable and non-toxic — perfect for baby-safe amigurumi.

Project tips from the studio

  • Use a hook one to two sizes smaller than the yarn label recommends. Tight stitches prevent stuffing from showing through, which is the #1 cause of 'my amigurumi looks scruffy.'
  • Cotton yarn beats acrylic for amigurumi. It shows stitch definition, doesn't fuzz, and holds shape after stuffing.
  • Stuff firmly and gradually — small pinches, not one big wad. Under-stuffing is why sphere heads flatten; over-stuffing in one spot is why they lump.
  • Position safety eyes BEFORE closing the head. Once it's stuffed and sewn shut, moving them is a project on its own.

Troubleshooting

The magic ring keeps loosening.
Cinch the tail extra tight, then weave the tail in twice — once one direction, once back. For heavily handled pieces, add a tiny dab of clear-drying fabric glue on the knot.
My decreases show as bumps.
You're doing standard decreases. Use the invisible decrease: insert hook into the FRONT loop only of the next two stitches, yarn over, pull through both, then complete the sc as normal. It vanishes into the fabric.
The head or body is misshapen.
Almost always uneven stuffing. Take stuffing back out and add it in small pinches while shaping the piece with your hands as you go.
Seaming looks messy.
Use the mattress stitch, which hides thread inside the fabric. Come up through the front loop only on each side, and pull snug every three stitches.

Frequently asked questions

What yarn is best for amigurumi?+

Sport or DK-weight 100% cotton. It shows stitch definition, doesn't fuzz, and holds shape after stuffing. Acrylic works but produces less-defined stitches; wool felts unpredictably when handled.

What hook size for amigurumi?+

One or two sizes smaller than the yarn label suggests. For DK-weight cotton, that means a 3.0–3.5 mm hook instead of the 4.0 mm the label recommends. Tight stitches prevent stuffing from peeking through.

Why does my amigurumi look lopsided?+

Usually uneven stuffing or a shifting round-start caused by not using a stitch marker. Restuff, and use a locking marker in stitch one of every round to keep the spiral straight.

Do I need safety eyes?+

Only if the piece is for someone over three. For babies and toddlers, embroider eyes with black yarn or embroidery floss — much safer and honestly gives many amigurumi more character.

How do I make amigurumi arms and legs?+

Most are small tubes worked in the round: 6 sc in MR, then continue in sc without increasing for the desired length. Flatten the top and single crochet through both sides to close, then sew to the body.
