Thanks. I didn't think about the warping problem. When I am machine quilting I put my big ironing board behind my cabinet. It gives me just enough extra space and helps with the drag. When I want to sew on the binding I have to take the ironing board out to iron the binding in half and then put it back. That is the time I'd like an extra ironing board. I thought a tabletop one would be just the thing.
And thanks for the ideas on making my own. I think that is the way to go.
