MaggieLou, I bought tables 2'x4' from Sam's Club, to back up to my commercial machine tables for more space.
I took the plastic feet off, measured how much of the legs had to come off to make the tables the same height as the sewing machine table.
You can then cut the legs off with a hacksaw or an electric SawZall. Put the feet back on and you're all set.
I put mine in a corner situation so nothing would fall to the floor.
2 more tips... A long handled pick-up tool. A telescoping wand with a magnet on the end.
JoAnn's had a great one, but when my builder son saw it, he said, "Thanks, Mom"
