I have finally finished my entry for the CGOA design contest! The final touch was sewing on the snaps. I just didn't feel right about using shiny metal snaps, so I did a little research and decided to cover the snaps with a coordinating fabric. They added a design element instead of taking away from the overall design. I will definitely be using this technique again!
To cover snaps, cut a circle of a lightweight fabric that is large enough to wrap around the snap easily with out adding bulk to the back (about twice the diameter of the snap). A tip when choosing a fabric is to put a piece of fabric between the snap halves and try to snap them. If they won't stay shut reliably, try a thinner fabric). Make a small running stitch around the outside edge of the circle, insert the snap inside and gather it up. Poke the "point" of the snap through your fabric. You may have to push aside the threads with an awl or large needle, or it may just go through on its own.
When you have this done, cover the female half of the snap the same way. You do not have to make a hole in this fabric circle. Put a tiny dab of craft glue in the center (the type that dries clear), and when it dries, you can snap it to the other side of the snap and it will make its own hole. The glue will keep it from fraying. I also put a little glue on the back of the snap to secure it. Place snaps on your garment and stitch in place. You may stitch through the snap holes and the covering fabric, or just through the fabric.
