I found a pattern online similar to this. The actual template is an old CD. I made a bunch of them out of christmas material last year for my quilting friends. The coasters fit around the wine stems, or you can just set the glass, etc on top of the coasters. they were fun to make. I also made some hot pads out of the same materials to place on the table. They were well received and fun to make. Cutting the circles was a pain, but worth it.
