I recently finished sewing a load of small human bodies. Here's the basic process:
1. Cut out the heads, and cut out the bodies.
2. Sew heads pieces together.
3. Sew body pieces together.
4. Punch in safety eyes.
5. Stuff heads and bodies.
6. Sew keychain hook into top of heads.
7. Sew heads onto bodies!
8. Dress, wig, and add the bling.
Most of them ended up as Harry Potter characters. ;D
