How to Sew Amigurumi Pieces Together

Crocheting the pieces is the fun part. Sewing them together is where a lot of crocheters slow down, because a wobbly head or a crooked ear can change the whole look of a toy. The good news: one basic stitch, a few pins, and a little patience will give you seams that almost disappear.

This guide covers how to sew amigurumi pieces together, from attaching an open-ended arm to a round body, to joining a heavy head so it doesn’t flop, to sewing flat ears that stand up straight. It works for any stuffed animal or small character pattern.

What You’ll Need

Tapestry needle with a blunt tip (a bent-tip one is extra handy)
Straight pins with large heads, or locking stitch markers
Scissors
Your finished, stuffed amigurumi pieces with long yarn tails
Polyester fiberfill for topping off pieces as you sew
Optional: sewing clips to hold flat pieces in place

Before You Start Sewing

Leave long tails. When you fasten off a piece that will be sewn on, leave a tail about 12 to 18 inches long. It is much easier than adding new yarn later, and it matches the piece exactly.

Know the two kinds of edges. Most amigurumi joins fall into two groups:

Join type	Example	What you sew through
Open to closed	Arm, leg, snout or tail onto a body or head	The last round of the open piece and the surface of the closed piece
Open to open	Head onto a body when both have openings	The last rounds of both pieces, stitch for stitch
Flat piece	Ears, wings, flat tails	Both layers of the folded edge plus the surface of the head or body

Pin everything first. Before you sew a single stitch, pin all the parts in place. Look at the toy from the front, sides and back. It is much easier to move a pin than to undo a seam.

How to Sew an Open Piece to a Closed Piece

This is the join you will use most, for arms, legs, snouts and tails.

Step 1: Stuff the piece as your pattern says. Leave the top rounds of a limb a little softer so it sits flat against the body.

Step 2: Pin the piece to the body at all four sides: top, bottom, left and right. This keeps it from sliding while you sew.

Step 3: Thread the tail onto your tapestry needle. Insert the needle under a stitch on the body, right next to the edge of the open piece.

Step 4: Bring the needle through both loops of the next stitch on the edge of the open piece, going from the outside in.

Step 5: Go back into the body right next to where you came out, slide under one stitch, and come up again beside the next stitch of the open piece.

Step 6: Repeat all the way around. Pull the yarn snug after every one or two stitches. The seam should close up and the yarn should sink into the fabric, without puckering.

Step 7: Before the last few stitches, check if the piece needs a bit more stuffing. Add it now, then finish the round.

How to Sew a Head to a Body

Heads are heavy, so they need a stronger seam.

Step 1: Stuff both the head and the body firmly. Add extra fiberfill at the neck area of both pieces. A soft neck is the number one reason heads flop.

Step 2: Line up the head and body. If both pieces have openings, match the last rounds of each so the stitches meet. Pin all the way around.

Step 3: Sew stitch for stitch, going through a stitch on the head and then the matching stitch on the body. Keep the yarn tension firm.

Step 4: Before closing the last inch, push more stuffing into the neck with a chopstick so it is packed tight.

Step 5: Finish the round, then go around a second time if the head still wobbles. A second pass makes the neck much stronger.

How to Sew Flat Ears and Wings

Step 1: Flatten the open end of the ear. Most ears are sewn on folded flat, so the last round lies in a straight line.

Step 2: Pin the ear to the head, checking that both ears are on the same round and the same distance from the eyes.

Step 3: Sew through both layers of the ear edge and under a stitch on the head, working along the line.

Step 4: For ears that should stand up, sew along the front edge and then back along the back edge. Two lines of stitching keep the ear from flopping forward.

How to Hide the Tail

A neat finish is just as important as the seam.

Step 1: After your last stitch, insert the needle right next to the seam and push it through the toy so it comes out somewhere on the other side.

Step 2: Pull gently and snip the yarn close to the surface. The end will slide back inside the toy.

Step 3: For extra security, tie a small knot close to the fabric before you bury the tail. Gently tug the knot so it pops just under the surface and hides.

Common Mistakes (and How to Fix Them)

Not pinning first. Pieces slide and end up crooked. Pin every part before you start, and look from all sides.
Wobbly, floppy head. The neck wasn’t stuffed firmly enough. Add stuffing at the neck and sew a second round around the join.
Seams that pucker. You pulled too tight. Loosen a few stitches with your needle and keep the tension even.
Visible gaps between pieces. Your stitches are too far apart. Work into every stitch of the open edge, not every other one.
Using the wrong yarn color. A contrast color shows every stitch. Use the tail of the piece you are attaching, or match the color.
Limbs that stick straight out. They were stuffed to the very top. Take out a little fiberfill near the opening so the limb lies against the body.

Tips

Sew in good light and take breaks. Rushing is how crooked ears happen.
Use a bent-tip tapestry needle. It scoops under stitches easily without poking through the stuffing.
Sew symmetrical parts at the same time. Attach one arm, then the other right away, so they match.
Count rounds to place parts. “Arms between rounds 18 and 19” is much easier to match than eyeballing it.
Take a photo before sewing. It helps you see if something looks off.
For toys that need to stand, sew the legs on while the toy sits on a flat table, so all feet touch the surface.

FAQ

What stitch do you use to sew amigurumi together?
Most crocheters use a simple whipstitch: the needle goes through the edge of one piece and under a stitch of the other piece, again and again around the join. When you work it close to the edge and pull it snug, the seam sinks into the fabric and is almost invisible.

Should I stuff before or after sewing amigurumi?
Stuff before you sew, but leave a little room to top off. Fill the piece, sew most of the way around, then add a last bit of stuffing before you close the seam. Once a piece is fully sewn on, it is very hard to add more filling.

How do I keep the head from flopping?
Stuff the neck area of both the head and the body very firmly, and sew around the join twice. Some makers also use a bigger last round on the body or a larger contact area, so the head has more to rest on. Pinning all the way around before sewing helps too.

Take your time with the pins, and sewing will become the step where your toy finally turns into a real little character.
