A lot depends on the amount of quilting you plan on doing. I just finished hand quilting a 78 x 90 applique quilt and it took me approx 5 mos working pretty steadily. Howver, I quilted undulating feathers on 4" sashes and Amish feather border (feather and cable) on an 8" border. I must say I was glad to put the last stitch in that one.LOL
