The source of inspiration for creating the сoaster is a real oak leaf that I found in the park. I think it has a nice shape and the right size. So I dried it, and made a sketch.

In this pattern I tried to create the natural “vein” of the leaf.
The сoaster can be used as a cup holder, table setting or room decoration.
