Wanted to play with new materials and discovered felt - cuts great and is amazing for Coaster. I loved Animal Crossing during the Pandemic and thought the leaf would make a a great coaster. And it does. I do prefer the one with the inner part cut out - but you can also have it filled if you prefer it. Both versions are avileable. Cut from green 5mm felt - should be between 1/8" and 1/4" in thickness.
