Which of 4 cotton sheets and 6 cotton sheets is easy to wrinkle after washing?

6' s sleep and 4' s cotton four-piece suit, their four-piece suit of cotton is relatively thin, but the softer cotton with 6' s cotton is more dense to keep out dust. Actually, it depends on everyone's liking and liking type. I am woven with rhombic yarn, because my daily bedding is 4-seeded, and it is easy to clean and wrinkle.
