So in cleaning my garage recently I found probably around 50-70lbs of 100% wool strips ready to be made into braided rugs. My grandmother used to make these and this was her stash. The problem is they've been sitting there for so long they smell musty and have a ton of dust, drywall dust and even some mud (wtf?) on them. I'd like to wash them before I get started braiding but these seems like a huge task and I'm really sure the best way to go about it.
The best I could come up with is soaking them (in a mesh bag) in cold water int he washer, doing 2 spin cycles and then popping them in the dryer with no heat. I know they might felt a little but that's okay. I don't have a clothes line to air dry and the image of having streamers of wool strewn about the house drying seems amusing but a terrible idea.
Does this method sound reasonable? Any other suggestions?
