This is a boppy cover I made for my sister-in-law, Spring. I just got my cover out and copied it. I had a zipper on the back but didn't like it. So I ended up putting a strip of velcro on the back, which I'm not sure I like either, next time I think I'll try snaps or buttons. Make Your Own Baby Stuff does have a boppy pattern if you want to give it a try.
