Low price option would be to purchase a couple of small drawer units of the right height (or two drawer file cabinets) and top them with a hollow core door. (Our local shop has seconds on the hollow core doors for less than $10.) That way you get a six foot by two or three foot work area, room for sewing, cutting and ironing. I made a removeable ironing surface from a 2'x2' scrap of thin plywood covered with 2 layers of cotton batting (or an old mattress pad would do, and topped it with the material you can get at the fabric store for ironing board covers.
