I love these sheets from the satiny texture to their light weight. I can appreciate the previous reviewer's comment about wrinkles but I certainly don't notice them whether I'm lounging in bed or sleeping. I too used to iron my sheets and pillow cases but common sense finally prevailed - when the bed's made the sheets are covered by a comforter and no one knows about the wrinkles but me.
Love the lightness of the sheets - definitely a hot-weather sheet. There is no getting around the wrinkles. I do iron the fold-over on the top sheet and the pillow cases.
