Step 12: Attaching the Arms & Tail
There are two ways to attach your limbs. One is to cut small slits on the monster's body and pass the limb through and sew from the inside. This is the more difficult way to do it.
The other way is to simply pin the limbs where you want them (on the outside of the body) and sew them on.
You have to be careful to keep your knot clean, but this way gives your sockmonster a very "I-made-this" look. If you decide to sew the limbs on the outside, go ahead and stuff the monster's neck and torso first, but don't do anything with his legs just yet.
After you've pinned the limbs, go ahead and sew them on.
