Choose from a variety of no-sew snaps. Some have colorful and decorative caps or rings that will show on the outside of the garment. Refer to your sewing pattern for instructions on choosing an appropriately sized no-sew snap. Make sure the snap is in proportion to the garment being sewn and that it matches the fabric. Make sure you have the appropriate snap-setting tool on hand.
Most snap manufacturers offer a setting tool made especially for their snaps.
Some snaps are pounded in with a hammer, and others are pressed into place with a tool that resembles a pair of pliers. Purchase extra snaps and practice applying them to a piece of scrap fabric before you apply snaps to your garment. Mark the placement of the snaps on the overlapping piece of fabric. Be sure that the marks are set an appropriate distance from the fabric edge and from one another. Use your sewing pattern instructions as a guide, if applicable.
