I was just going to return 2 of the 3 sets I bought, because I used the one set for a month and do not like them. My PJs stick to them making it hard to turn and they are very hot! They also have a weird feel to them. I am upset that the window to return them has expired I did not know there even was a window. Going back to 100% cotton! put my old sheets back on and had a great sleep!
