I like the new quilt look so I don't wash mine. So far mine have been for family and no one is allergic to dogs. I did throw one in the dryer with a fabric sheet because the back was less expensive fabric and thread clippings were sticking to it. I trust my sewing and my machine, so I feel no concern about undone seams. I do include 2 color catchers with every quilt, but all fabrics that may bleed have been prewashed.
