1. Coat the switchplate with glue. I used Elmer's and I didn't dillute it with water or anything else. I just squirted some on and used my finger to smear it all around covering the entire surface right up to the edges.
2. Apply fabric to the glue. Don't worry about covering up the holes because you can cut those out later. Fold the fabric around the edges.
3. Apply more glue to the top of the fabric. Once again I just squirted it on and used my finger to spread it everywhere. Make sure you get the edges where your fabric folds around to the back!
4. Let it dry. I put mine on the deck in the sunshine to speed up the process. Once it is dry, you can punch the screws through the screw holes (the fabric will give easily now that it is hardened with glue). I poked a hole through the center with some scissors and trimmed the fabric back to make room for the lightswitch.
5. Now you can mount it on your wall! I did mine so that the switch came through one of the skinny towers on the fabric. This fabric matches a lot of the decor in my son's nursery. Such a simple project!
