For this project I provide 2 variations. One is with my own drawing of my beaver and the othe more of a wood slice. 

And to make it a perfect fit, the coaster shape itself is a wood slice.

Red = Cut

Violet = Score

Glue the border on top of the plate and your done. Make sure to match the outer cut line. 

I really love this one as it's including my little beaver drawing and I now finally own a tray to hold my nails when doing string art. I hope you like this idea and have fun using it for your own! ~Anzy
