all my fabric stops @ the washer on my way in the house.. i wash it all in hot & dry on cotton... if it bleeds after that i will use retayne, but never have any shrinkage after that..
also, i have allergies so i have to wash it all.. and i work for a trucking company & i know how dirty the dock is, and any fabric you buy from anyone, has been dlvd on a truck, therefore, must have been on a dock... that dust goes thru everything!
