My instructor at my LQS had a quilted sewing kit that a friend made her. I would like to make one for myself. I am not sure that I want to use sandwich bags for pockets as I am sure I will wear them out in a jiffy. Hers had a zippered pocket, a built in pin cushion, and maybe even another pocket or 2. I think I should be able to design one myself but don't trust my judgement. Any suggestions....
