I was looking forward to usethese sheetssince the fabric is quitenice and elastic only for it to end upin such disappointment. The fact that the full-fitted onesdonot fit so wellour full sized mattress makes it really frustrating. While we are sleeping, it starts toslipping off and coming totally off the corners. The flat sheet also appears to be too tiny for a full-size bed. I've never had this problem with other full-sized sheet sets, so it's a little disheartening.
