I sliced these coasters off of scraps from the legs I made for my future tv stand shown in pic 2. They are made of 3 red oak boards laminated together. I stained them and finished with Deft spray. Also added some felt to the bottom. After friends and family saw these they all want some so a real quick simple project is turning into work for a few days. But, they are kind of cool and different, so I guess thats ok. Problem is, I ran out of those particular scraps so now I'm gluing up more scraps to make more coasters..
