I ordered two of these thinking they were cotton fabric on the outer layer and poly on the lining, but it must be some kind of poly/cotton blend that really cheapen the quality of the shade. I really love this style but unfortunately had to return, (accidentally bought one at clearance and I was unable to return - marked in very fine print that you actually had to click through a link to see) so we are left with one that Wayfair would not accept. For the price, these are not worth it.
