I tried so hard online to find just a fitted sheet--not a set. Finally I found what I thought was one single fitted twin sheet with 2 pillowcases. Although I didn't need the pillowcases, I ordered it. Lo, and behold, it was a set of top and fitted sheet. I'll have to give the top sheet away since I have no use for it. To return is difficult at this time. Can't get to the post office. The fitted sheet is OK but I would rather have paid that price for just one good quality sheet than two sheets.
