1. Decorate your cape and mask. We used a Walmart cape and mask set (about $5). They come in black, blue, red and green. Target has a cape with a wrap around front with muscles (about $5). Decorate with foam letters. I had each child's name ready to go, organized in an ice tray to make things fast and easy. All they had to do was peel and stick. No searching for letters or fighting over colors.
