You just described my sewing table is.... the iron base of an old treadle (with treadle removed) with a white and red enamel top..... I spotted it at a flea market and paid $50 for it, and before I could get it back to my car I had several women offer me twice what I paid for it, but I just smiled politely and said sorry, she's coming home with me.
