Quilted these for a friend of a friend and they just about killed me! They were both like 70x80 give or take a couple of inches and my back is paying the price. With my little machine, it took me a total of no less than 7 hrs of standing behind the machine, working the shoulders, back and every other muscle I haven't used in a while. 2 days in a row. There are 2 more she gave me to do, but i just can't do it. Not with my little machine. I'm beat, heat that spa up baby, because here I come... If I could just get there!
