I purchased an av cart from our school district after we closed 3 elementary buildings. I cut my piece of plywood about 30 x 40. I covered it with batting and then the thermal stuff and covered it with a nice cat print. I attached guides on the bottom so it stays put on the cart. I love it!!! And, I think because it can easily be removed that I will make another in the same fashion for the cutting board. Total cost of wonderful ironing board was about $20.00
