Miles-a-saurus Costume

My son has been infatuated with Spinosaurus since he was 2-1/2 years old. He's 5 now and still loves this dinosaur. I'm no artist, but my son loves drawing so I would sit and draw or do chalk with him outside. The more I drew the better I got. Not great, but just better than drawing stick figures. One day I happen to sketch Spiny's head on cardboard and thought why not make a mask for him to play in and this happened. I had no pattern and just did the best I could using cardboard, foam padding, fleece fabric, and tons of hot glue stick. I just finished up this costume last night and he was the happiest kid on earth!
