What are you most proud of? That they look just like I want them to and they stand up nicely. I managed to be able to make one of these in about 1 1/2 hours. What advice would you give someone starting this project? Canvas and upholstery fabrics work well for this project. It's easier to make if you use a zipper 3 or 4 inches longer than necessary. Easier to sew in and much easier to press and top-stitch next to the zipper.
