A very clever mom did THIS with a simple pair of socks
Now pick one sock and turn it over. Use scissors to cut the seam of the sock and turn it over once more. Put a little bit of wool inside to make the head of doll. Use a string to attach the neck and make a knot. You can also use a plastic straw.
Put a little more scraps of wool inside the body of our doll and press hard inside as shown on the picture because afterwards you'll need to sew one arm of the sock that you did before.
