In addition to bleeding, chemicals and shrinkage, think about where the fabric has been on its journey to your home. It may have sat in a factory or warehouse before being loaded on a cargo ship, sat in port for a few days before being loaded onto a truck. Then to a warehouse and finally shipped to a store. lots of opportunities for lots of little critters to contaminate it. Then to the store where customers (and sometimes their pets) can touch, sneeze and cough on it. Looks beautiful but I will wash mine just in case.
