This costume took me 14 hours to make! I used cotton flannel in purple and mottled green, and drafted my own pattern based on 12 month sized pajamas. (It was actually too small around the thighs at first so I had to add a crotch panel.) The tail and head crest are stuffed with polyfill. It closes with a zipper which runs up the right side seam and curves to the collar. The hood is attached.Whew! Jack was such a good sport and wore it ALL DAY at the convention with no problems. I'm glad that I decided on flannel because it wasn't too hot like fleece would have been but it wasn't too thin and flimsy like a cotton print might have been. I've already washed it three times and it's holding up great!I will try to upload a pattern or basic sketch of how I made it in the future. Let me know if you want it!
