I've heard some of the ladies handwash and use one of those lettuce dryer spinny things to wring the water out. Can you tell I don't own one of those? Then hang the pieces to dry and/or iron dry. Personally, I always have bought yardage and prewashed then cut. I suspect at some point prewashing becomes a bad idea (I am one of "those" people. I think everything should be prewashed but at some point ...)
