If you're working with thick fabric, such as Chinese prefold diapers or double layers of marine vinyl, you may find your snaps are falling off. That's most likely because the snaps are too short for the fabric thickness. If size 20 standard prong snaps are too short for your embroidery, diaper, or other project, try our size 20 long prongs instead. Now offered in a multi-color pack of 11 popular colors for a limited time. Available only at KAMsnaps.com.
