Beautiful set. Yes the sheets are polyester and cotton or a cotton blend would be much better, but the sheets are still nice. I bought some flannel sheets to use in the winter and I'll use the polyester ones in the summer.  Comforter is absolutely adorable and great quality. Made the mistake of ripping the tags off the small owl throw pillow and it ripped all along the seam...luckily I sew.  Was shipped from the states and took 11 days to get it. Would definitely recommend.
