Step
2

Cut out and assemble the pattern

2-1
Cut out the pattern

Cut out the pattern along the cutting lines.

2-2
Overlap the tabs and tape them

Overlap the tabs with matching numbers and tape them together.

2-3
Cut out the other pieces the same way

Cut out 4 types of pieces in total the same way.

Step
3

Cut out the fabric

3-1
Cut two pieces each of Outer A, Outer B, and Lining A

Cut two pieces each of Outer A, Outer B, and Lining A.

\ Point /
Cut as many pieces of fabric as the pattern indicates

For example, if it says “×2,” cut one piece for the left and one for the right, for 2 pieces in total.

Step
4

Mark the pattern

4-1
Cut away the seam allowance at the dart

Cut away the “seam allowance” inside the dart on the Outer A pattern.

4-2
Layer the pattern and fabric, then trace the dart

Layer the Outer A pattern you trimmed the “seam allowance” from onto the fabric you cut in step 3, and trace the dart.

4-3
Snip the notches

Make snips about 5 mm long at the notches to mark them.

4-5
Trace the darts and stop-stitching points on Lining A

First, trace the 3 darts on Lining A.
Next, trace the 2 “stop-stitching points.”

Step
5

Sew

5-1
Sew the darts

Baste the 2 darts on Outer A, then sew along the lines you traced in step 4.

\ Point /
Don’t backstitch at the dart tip

At the dart tip, don’t backstitch. Instead, leave the thread a little long, tie it in a firm knot, and you’ll get a clean dart.

5-2
Sew the Outer A pieces together

Once the darts on Outer A are sewn, layer the left and right pieces with right sides together and sew down the center.

5-3
Sew the Outer B pieces together the same way

Sew the darts on Outer B too, then layer the left and right pieces with right sides together and sew down the center.

5-4
Sew Outer A and B together

Layer the Outer A and B pieces you just sewed with right sides together and sew all the way around.

5-5
Sew the “darts” on Lining A

Baste the 3 darts on Lining A, then sew along the lines you traced in step 4.

For the lining, it’s fine to backstitch.

Once sewn, sew the darts on the other piece the same way.

5-6
Layer the two lining pieces and sew the “head”

Layer the two lining pieces with right sides together and sew the “head.”
Don’t sew between the “stop-stitching points,” leaving an opening there.

5-7
Sew the outer and lining together

Insert the lining through the opening in the outer, layer them with right sides together, and sew all the way around the face and neck.

5-8
Snip into the seam allowance

Snip into the seam allowance around the face and the neck so the fabric doesn’t pull when you turn it right side out.

5-9
Trim the corner seam allowances too

Trim the seam allowance at the corners so they come out cleanly when you turn it right side out.

Step
6

Turn it right side out

6-1
Turn the fabric right side out through the lining opening

Reach in through the lining opening and turn the whole thing right side out.

Step
7

Attach the hook-and-loop fastener

7-1
Cut the hook-and-loop fastener to 3 cm

Cut a 25 mm-wide hook-and-loop fastener to 3 cm.
Rounding off the corners keeps it from hurting if it touches your skin.

7-2
Sew it onto the belt at the neck

Sew the hook-and-loop fastener onto the belt at the neck.
Attach the “hook side” to the outer and the “loop side” to the lining.

Step
8

Add the stuffing

8-1
Add stuffing through the lining opening

Stuff little by little through the opening at the back of the head.

Step
9

Close the lining opening

9-1
Sew around the lining opening

Fold the seam allowance around the lining opening in by 1 cm and baste, then sew along the edge with the sewing machine to close the opening.

Step
10

Finished
