I got mine at Bed Bath & Beyond and I know I was looking for high thread count but i dont recall the tag has 100%cotton. They are so soft. That reminds me of the nightmare when i went to Fla to see a pain Dr. I stayed with my Grandmother who had pilly sheets and both legs flared up and i wanted to come out of my skin! Now I know if i travel i have to bring my own sheets. momof4
