I washed pendleton wool yardage in a wringer washer and dried it in a dryer
whenwashing wool:
wash and rinse it in the same temp water (tepid - human body temp)
avoid a lot of agitation
dry on a moderate heat and remove the fabric from the dryer when barely dry.
I washed five yard lengths ( I did hold my breath while doing this! ) and it turned out great.
I was going to make shirts for DH and did not want to have to take them in to be dry cleaned.
