I NEVER let a quilt go without washing it first, gift, sale, donation it does not matter. For me the final step to every quilt is laundering after the binding is finished. I've never had a new, laundered quilt look ( used) either. Laundering removes any soils/oils/chemicals and marks. Allows me to be sure every seam, stitch is secure and no colors are ( troublesome) . every quilt, every time... No matter what!
