These were all just all leftover rings from my lidded boxes. Instead of just throwing them out, I decided to find a use for them. I made them into little change dishes. They vary in size but are about 4 inches in diameter and stand about 1.125 high.
The interiors are some very stiff felt I found at Hobby Lobby. I can cut it on our laser so they are perfect circles and to the exact size they need to be.
