The set washes up beautifully.  In fact, it is important to launder it before using, because this helps the pattern to puff up and not just lay flat.  It would be helpful if the shams had some kind of fastener (Velcro, zipper, snaps, etc.), since the cross-over flap doesn't stay closed.  I used safety pins, but it could also be closed with a basting or running stitch.  The set looks very nice in my seaside style bedroom.
