I was at the dollar store and they had these small turntables and the light bulb lit up. I bought one and then bought a 6 x 9 mat at JoAnn's with a 50% coupon. Superglued the mat to the turntable, and voila! a revolving mat for about $4.50. I was doing a BOM using the Marti Michell templates, and it worked just great.
