This is a surprisingly easy DIY project, that you might be able to make for free if you have some epoxy left over from an old project. I took some old cedar fence panels, burned them with propane torch, then covered with epoxy. What I got was a pretty cool 3D wood and epoxy coaster unlike any I had seen before. Hope you like it, let me know if you have any questions!
