1. Load the Hobbs cotton batting into a TOP LOADING washer, evenly distribute the mass.
2. Fill washer with lukewarm water.
3. Agitate the machine BY HAND a couple of times or push the batting up and down to thoroughly wet it, DO NOT let the machine cycle.
4. Let it sit for a few minutes (5-15).
5. Set machine to spin cycle/gentle to remove water.
6. Fluff in an AIR COOLED dryer (no heat) for about 5-10 minutes.
7. Remove from dryer immediately and drape it over the floor, sofa, table, whatever, overnight to finish drying and to remove wrinkles.
I've done many, many of the Hobbs 80/20 battings this way over the years with no problem.
