I just washed them and they seem like true percale sheets. I needed a set of cool sheets and did my research on percale sheets. I bought these because they’re 400 thread count and they were within budget. They will wrinkle because they are cotton. I did have to iron the pillowcases like I do with all my cotton pillowcases. That’s not a big deal. They are a crisp cooling cotton that I was looking for. I ordered the blush queen set. The color is more of a light peachy pink. It’s not as blush I had hoped for. I love that the fitted sheet is labeled top/bottom and the wide elastic fits snug on my 12 inch mattress. So far so good!
