to Nikki,
If you wash your wool before you cut it up and make the quilt you most certainly can wash the finished quilt. You take the quilt to a laundramat and wash it in one of the big load machines that tumbles the items in a revolving tub of water. Use lukewarm or cool water, gentle cycle if available. The dry the quilt in one of the huge dryers ON LOW HEAT.
Trust me, it works. I've done it.
