Every quilt I make is laundered as the final step after binding. I launder them the same way I expect the recipient will. For kids quilts I toss them in the washer, normal ( always use) detergent, warm water, regular cycle. Then I toss them in the dryer, regular cycle. I've never had one damaged, ungiftable, and I know that it is going to be OK for the child/family to use, launder without mishap.
