A shark costume can be made without having to do a lot of sewing.
Step 1: Make the fin
Put a ball point needle in the sewing machine. Cut a white triangle, about 1-foot tall. Sew around two sides. Stuff foam in the fin, making it about 1-inch thick. Stitch the open edges to the sweatshirt's back.
Step 2: Make shark teeth
Cut 3-inch strips of white, long enough to cover the front edge of the hood. Next, cut 1-inch zigzags on one edge of the strips. Overlap the flat edge of the strips with the inner edge of the hood, and stitch the teeth in place.Learn more about Sewing
