I made this double cape for my son after my sister made one for his brother. Choose the character you want to do and pick out the fabric. Then cut out the front and back pieces the same size. I used black bias tape for the neck, and black fabric for the strap with velcro. Just make sure when sewing it togther that you don't sew the circle until you've turned it right side out. then sew on the neck and strap. I then cut out the symbols from felt, using pictures I found online to make an outline.
