These are nice, roomie sweaters. The patterns are unique and beautiful. They recommend washing alone. I would agree on this. The first 2 sweaters I purchased, I washed and dried alone. They did not shrink in the dryer. Then I ordered more and mixed with my regular laundry. These are part wool and the fibers stick to every other piece of clothing. I could not get the fibers off of my black t-shirt that was in the wash with the sweaters. Wash alone and dry separate!
