My guild did the jelly roll races for our community quilt workshop this year. Starting with all the strips sewn together and ready to sew, the first to have her quilt sewn was in 18.6 minutes. the second was 18.9 and this one was pin basted before wewere through. these two gals sewed 2 more apiece in our time frame of 3 hours. One lady did get hers sewn, basted quilted and bound in the 3 hours. These were lap size quilts. It can be done by some. Just not by me. My top was done, but I still have to baste, wuilt and bind mine.
My DD came in 3rd at 19.2 minutes. hers is up to quilting now.
