I am very disappointed in the quality of Casserly Percale Sheets, full size.  I washed sheets twice to soften and ease out some of the wrinkles to no avail.  Since I washed them to prepare for use they can't be returned.  I prefer cotton sheets, none of my other cotton sheets are this difficult to put on bed.  I have to iron pillow cases and top sheet hem in order  to look comfortable, smooth and welcoming.  Do not recommend this product.
