In summer lay bedsheet outside on grass on a breezy 85 degree day. Put wet quilt right side down on sheet. Lay another sheet on top. Leave until mostly dry except for edges. finish drying in the house spread over a sofa/chair for 48 hours. Never agitate in washing machine. Don't put in dryer. You can let a quilt soak in the machine, add soap (Orvus or Ivory hand dish soap) and agitate by hand, spin out water, rinse, and spin out water. Just don't let it agitate. The judge said that spinning won't hurt the quilt.
