You can also purchase a long PVC pipe, cut into equal sections and drill a hole at your preferred height and put a long stove bolt through the pipe and secure with a nut. Get someone to help you to raise your table and drop the legs down into the pipe. Voila! just the height you need to save your back. Center the quilt on the table, clamp, and baste, using your method of choice. It won't take more than a half hour to measure, cut, and drill the holes in the pipe and fasten the stove bolts (or carriage bolts) through the holes. We liked them so much that at church, we leave them in the tables so the seniors can get to the pot luck dishes easier. Hope this works for you.
