One of the tadpoles I made! Only brought one with me to Megacon. I have two. They're mini soccer balls that I covered with a 7-piece sphere, then hand-sewed the tail (my favorite part) and the face on. The face pieces are all double-layered (except the pupils) and fused with Wonder Under before I attached them. The lips are attached to the teeth with a small zigzag stitch; same with the pupils. The seams are under the mouth so I can easily remove it if I need to pump the ball back up.
