I bought an ironing mat from Joanns with a coupon. I wish I hadn't. It has a layer of foam on the bottom and the shiny silver stuff, like ironing board covers, on the top. I use it on the end of my cutting table at my vacation home. I really hate it. It 's too puffy so it can be hard to get a crisp flattened seam. It also slides around. The silver part is ok, I don't mind that. I wish that I'd bought batting or something else with my coupon and made a big board instead. Making one is on my list of things to do.
