I am in the process of making my first one. I put a zipper in but now that I look at picture and think about it I don't know how that will work since the ends get tucked in with the bows and my zipper goes from end to end. Hmmmmm I'm also having problems with the straps. Someone on here said how well it worked to use the no-roll waistband elastic in your straps. Well, it looked fine on the top but when I turned it over the elastic had pulled through the fabric and the thread is all messed up. So then I tried just making it with batting inside. The fabric started getting pushed up so I used my walking foot. It made teeny tiny stitches so I quit. People on here whip them out one after another and I can't even get one made!
