I have done that too but have read on some posts at differing sites that using sheets is a no-no because of the increased thread count. I haven't had any problems. Have you or anyone else. I actually found some at Ollie's, an outlet for a price too good not to try. Only one had a problem...the sides were missing the hemming or salvage...not a problem for me. Most I have bought were 250-300count. Thanks, I appreciate some feedback from anyone who has used these.
