These linen sheets are of exceptional quality. They feel stiff coming out of the package (as all linen sheets do). Washing them frequently is recommended. These sheets can’t be transferred directly from the package onto the bed. They have a horrific smell upon unfolding them. 
One good washing with a ‘bounce sheet’ in the dryer takes care of that. I have bought many different brands of linen sheets over the years. This purchase was by far the best with an exceptional price.
