Bandage Protector: This is what I used for my kids when they had hand injuries. Cut a small hole in the heel for a thumb, cut the foot piece down to size to keep the bandage clean.
Duster/Polisher: Two socks for this - pop on your hand and get to work. I use this for the multitude of odd socks I have about the place. I love to use them restoring vintage/antique sewing machines.
Baby booties: Use these as mittens to shop babies scratching their faces.
Mini Christmas Stockings: attach a small paper/cardboard Xmas motif to the outside with a small safety pin.
Dolly/Teddy Hats/Headbands: Lay ght across from the heel to the top foot part. Tie near where you've cut, winding cotton round tightly to close the top of the hat. Use the ribbed tops for headbands/ belts.
