I think this one looks a lot better - no zipper across the top. The zipper makes much more sense to me inside the inner "U". I'm going to try to remember how to sew a zipper from my zipper clinic at Bolt!!

I'm not sure if there are other parts to this website? Would love for it to be a blog....
I'm headed to the fabric store to figure this little bugger out!
