These were scary when I first took them out of the package - they were stiff and scratchy. I almost sent them right back, but thought I'd wash them and see how they ended up. Wow...for the price, these are excellent. Soft, slick, and cool to sleep on, which is exactly what I wanted. I'm going to be buying more soon!
I bought these pillowcases because they don't cause my curly hair to develop knots overnight. I could have simply sewn some pillowcases, but didn't want to spend time on doing so as long as I could find some in the right color, and these come in lots of colors. They're a bit thin, as far as satin goes, and my cat has already snagged them multiple times, but they do work with my hair!
I got these to help with my bed head in the morning. They are very useful for this purpose. If you are buying them for decorative purposes I wouldn't sleep on them. They start to look very worn very quickly. But great for keeping your hair from looking like you've just been electrocuted.
