Just a thought here...if you have a front loader, I think this might be the one time to go to the laundromat...one with top loaders. Ask around and see where one is that has good hot water. Their driers are usually way too hot, too, and would be perfect for shrinking the wet wool.
Our washer decided a year ago that it didn't want to work. We fiddled with it, and switched the water hoses around, and when I switched hot for cold, it started working. Hey...I never wash anything in hot, so who cared....my washer worked, and I didn't have to buy a new one. So nothing would be getting washed in hot here.
