To tell you the truth I have never recorded how long it took to quilt a quilt on my DSM, or the amount of thread I used, maybe I should start. However, when quilting a larger quilt like a queen size or king size (Yes, I have quilted 3 or 4 king size quilts on my DSM), I will work short periods of time, 1-3 hours, then I need a break, so off and on sewing I would probably do a king size quilt in a week. I do have carpal tunnel, so I need to limit the amount of continuous quilting that I can do and it also helps with other aches and pains from getting older, not necessarily better. Well, there are a few things I'm definitely better at now that I'm older. LOL. On the very first king size quilt, I had a center medallion of pieced basket blocks, surrounded by plain blocks, which I quilted using a cable pattern in a circle. When there is no one to tell you that you can't do something, go ahead and do it.
