My wife came home with these lovely coasters from Bed Bath and Beyond the other day. They are made by Seattle based Tovolo, who makes a bunch of different kitchen stuff. These simple rubber coasters are just the thing to protect your nice wood tables. The colors are very nice in person. I especially like the fact that between concentric squares you can see the surface they are sitting. Of course the best part about them is the price. A set of six will set you back $5.
