Here's a set of coasters you will love. The wood is mainly off cuts from the creation process of all of my other items. Saved from the scrap bin, the burn pile, or the land fill and repurposed into something useful.

This is a for a set of four. They are going to be random in terms of what woods you will get. You probably won't get more than two that are the same. Common woods will be oak, maple, alder, cherry, and walnut. With that said, you may get some mahogany, poplar, honey locust, Kentucky coffee nut, and whatever else I have sitting around.

Each coaster is 4" square with a 3" circle in the center lined with a bit of cork for absorbancy. They are 1/2" thick, but with the chamfered edge they look thinner.
