Stop your cookies from sliding all over the place while working on them!
Place one mini mat on the surface you are working on, place your mini turntable on top and place another a mini mat on top. This will keep your turntable from sliding around and keep your cookies steady on top (also makes it easier to clean your turntable!)
Turntable is 4.25" around and 1/'2" tall. It turns on ball bearings. The mini mats are 4.25" in diameter.
