RCW, do you have a tall mattress? My fitted sheets fit fine, but my flat sheets always seem to come untucked at the ends because my like to have my sheets/covers, etc. up around my face when I sleep. Ultimately, that tends to leave the length of the flat sheet too "short" and it comes untucked on the sides and eventually on the ends. I don't really have a price range, though I do like egyptian cotton...soooo soft. I will pay for quality, here.
