My nephew had a Sponge Bob shirt that was too small, but he still wanted to wear it. So I made a doll with it. I designed everything on paper first then proceeded to cut everything out. You can use an existing pattern for dolls, but I chose to design it myself. I made a head, attached yarn for the hair, and then I used permanent marker for the face. I made arms and legs out of a muslin, and stuffed them with poly-fill. I used his shirt for the body, and stuffed it with poly-fill. He loved it and so did his sister, so I did the same thing for her out of her favorite shirt. I thought this way they could keep their favorite shirt and not wear it.
