Super Fast Hot Plates!

A few years back I bought these "wall tiles".  They were meant to go in my bathroom but the colors we just too off. So I have held on to them until it hit me.  I can use these as hot plates!

All you need is a tile, and four felt feet. ( These are the same ones I use under my furniture to not scratch our wood floors)

Now these won't scratch my tables...
