These sheets are 100% cotton from India. I prefer Indian cotton to Chinese cotton, its softer yet crisp and stronger in my opinion. Some people are saying these need to be ironed. Not true in my case. Perhaps they are drying them on a high/hot dryer setting?  I washed and dried them on the permanent press, warm/medium dryer setting. They came out fine and went right onto my bed just fine. Im a bit picky so I probably would iron the pillowcases only if guests are coming. By the way, Im definitely ordering more for the guest room.
