Step 4: Finishing up
I poked a hole in the top of the button with an awl to fit the loop for the chain which I formed with jewelry wire and needle nose pliers. I also painted the rim of the button with black paint because I thought the button might otherwise look too large (since black is very slimming). I also painted the backing to make it look uniform. Once the paint had dried I popped in the battery, but the backing on and it was ready to wear.
