As usual, when I buy linens, I pop them in the wash before using them the first time.  As I was putting them on the bed I double-checked the tag ... OMG ... they must have lost 10% in the wash!  The sheets are advertised as being 90% cotton - what I was looking for and the only reason I paid that price for the sheets.  But when I was making the bed I could see from the tag that they are only 80% cotton!  I'm sure Wayfair wouldn't have been false advertising so I guess that means they either lost 10% of their cotton in the wash, or the tag put on the sheets by the manufacturer, AND the package are both wrong.  I'm soooo disappointed - primarily in Wayfair!  Wayfair: Change how you are advertising these sheets!
