My record time is 1 week while working full time. The one for my avatar was done in 7 to 10 days piecing full time to make the top. Plus the design time and the quilting time. Longest was to finish my first quilt, 9 patch pieced entirely by hand on both sides, and tied, was 5 years whille going to school full time and working 3 of those 5 years. Average is a few months while working full time.
