That's is what I would like to do. What I am not sure of is do how do that. Do I make the zippered middle section and then sew another side to each side of the zippered section or do I fold the lining in to 3 sections and then attach the zipper to the top of the middle section? Also, where do I leave an opening in the lining in order to turn it? I know I am probably making this more complicated than it has to be, but I just don't know. :)
