-Hot glue gun
-Roll or piece of cork
1. Paint the outside of your embroidery hoop. 2. Trace the inside of the inner hoop onto a piece of foam board, and onto a piece of thin cork. Cut out both. 3. Apply a liberal amount of Mod Podge to the foam board, and glue it to the piece of cork. Make sure to apply a lot around the edges, and to match the pieces up correctly. You may want to place a couple of heavy things (books, weights, etc.) on top until it dries. 4. Place the foam/cork piece into the inner hoop, making sure it's flush with the edges. On the back side, use hot glue to secure it in place. 5. Place your fabric over the new cork board. Slide the outer hoop over the fabric and inner hoop. Pull the fabric tight around the edges, and screw the outer hoop until the fabric stays tight. 6. Cut the edges, leaving about two or three inches of fabric. Pull the fabric tightly to the back side, and hot glue in place. *Not going to lie; I just taped my fabric down in case I want to change it in the future.
