I did not pre wash my fabrics. I've been told to do so and not to do so by various quilters. So what do you recommend? (I always prewash if I am sewing a garment, etc.) My sewing machine is as old as the hills (not quite as old as me :), so your thoughts about seaming could be right on. My husband helps me with fabric choices and cutting. I could never piece a quilt if not for him (first of all, I would give up right away :D and I have absolutely no puzzlemaking abilities. I have a whole new appreciation for quilt makers!!
