Sewcrafty...I asked my DH if he couldn't just put up a plywood top with legs and he is considering doing that. Did you cover the top of the plywood so material would slide easily?
Vjengels: My room is about 10x10 but not truly square because of doorway, etc. but I do have a closet and I have 3 plastic shelving units in there for supplies, etc. My problem is I have a very large cutting table (36x54x36 high) that I had at our house in TX. I had a much larger sewing room so it was perfect but it takes up a lot of space so it doesn't leave me much room.
