Another option would be to purchase 1 or 2 Lifetime adjustable height tables, the size of 24 inches x 17-18 inches. Office Max, Staples, sometimes Costco, and such will put them on sale. I got my first one on sale for about $14 ... the price has gone up to about $19 on sale. I take these with me when I am working out of town. One for my machine and one for the extra fabric if needed.
