Bill's been busy adjusting my quilting setup. He added the heavy springs to the front of the sides to balance the added length that he'd added before. The marks let me see where I've raised to and the levels on the top allow me to raise the back level to the front. The tape measure that's attached to the outside is from the "old days" and is stuck too well to come off. The lifts are from Kathy Bowers with some adjustments for my frame.
