To try out first, I bought these pillowcases before decided to buy a whole set, we like percale sheets but some that we’ve bought were not exactly cool and made me sweat at night. I don’t mind their wrinkled to me is better cause that means it’s 100% cotton and not blend like wrinkle free. I’ve been using them for two weeks, washed twice and color hasn’t fainted. Since not longer feeling hot or sweating at night with these pillow cases, I’m not waking up throughout the night so improved my quality of sleep. I bought the alternative comforter waiting for arrival and will buy the sheet set and extra pillow cases.
