glad you asked! i turned some baby beehinds and a zigzag (wahm) cover into pockets by simply sewing in a lining, careful not to cover the snaps/velcro on the back wings. they are a little bit dodgy as i'm new at sewing, like the stitch is showing on one and my joins aren't perfect, but they work! and they fit really well. (the zigzag one was too tight over a nappy, but is perfect fit as a pocket)
