I have been wanting to get a set of these sheets, but the only color I want for my bed size is not in stock. 
Percale or Sateen? I don’t see mention, but I do like the crisp feel of Percale over Sateen
These are sateen. Apparently we rarely run percale sheets.
I bought these last time they were up; and I really, really like them! It’s hard to find decent sheets these days, especially online.
Are the matching duvets for sale? Please please someone tell me that I glanced over them while scouring the site.
Not that I’ve seen. Wootstalker.com is good for searching our sales.
Do they wrinkle a lot?
