I actually just used some batting I had handy. I didn't really feel like running out to the fabric store for this one. I only had enough to line the outside and the front pocket and not the lining. Well... I probably could have done the lining but I wanted to save my bigger piece for some quilts I'm working on. I'm probably going to get some fusible pellon for my next attempt. I want to make another wolf one for my friend who also loves wolves.
