I've never had a set of percale sheets and was a bit hesitant to buy these based on reviews that talked about the need for ironing. Although the sheets do wrinkle, if you take them out of the dryer when they're still damp, it cuts down on wrinkles. I did, however, iron the pillow cases and the top edge of the top sheet. The feel of these sheets is phenomenal. It's like sleeping in a bed in a lux hotel. My biggest complaint is that they are far bigger than my bed. I had to use a device to make the bottom sheet fit tighter. The top sheet is also very big. This would be my biggest complaint.
