Washed, as per instructions, prior to first use.  Worst set of sheets that I have ever purchased. Wrinkled beyond belief and flat sheet according to website and packaging is 106 inches long, after washing, flat sheet is 98 inches long. Shrinkage of 8 inches is completely and totally unacceptable.  I am very disappointed with this purchase as well as another set of sheets in the total order. 

Pros: None
Cons: See remarks
