I'm the oddball here in that I hate soft sheets. I love the old, scratchy cotton percale of the 50's and 60's. Sigh. I did manage, some years ago, to find some really nice ones similar at Kohls, I think Vera Wang. But the fitted sheets wore out and got soft from me sleeping on them. So I trashed them, and bought some that are just ok. As for flat sheets, I still have them, and my mom found me some on Etsy; brand new, in package, Lady Pepperall, crisp, white, and scratchy. Well, not really scratchy, but almost.
Still working on finding decent, but not that pricy fitted sheets like I like them.
