My husband made me one out of a cabinet that our old tv sat on. I'm not sure what the cabinet was for originally. It worked out great. It has a cupboard with doors on the bottom and an open shelf above that. I copied the idea from an online site. I thought maybe I still had it, but unfortunately, I don't. My DH made a wood frame on top of the cabinet and put a plywood piece the size I wanted on top of that. I then covered it with pretty thick batting and then insulbrite. I love it. It is so much easier to iron fabric on it and also it is thick enough I can pin items to it to make it easier to iron them, like binding.
