These were not acceptable at all. Included in the set were two pillowcases, one flat sheet and two fitted twin mattress sheets. I washed them all not realizing the fitted sheets were for twin mattresses I guess I could use them on the box springs. Since my cal-king bed is one solid mattress, they won't work - I don't know if I can do anything to make these one sheet - so I'll use the flat sheet and the pillowcases and use a fitted sheet that doesn't match in order to use the remainder of the set. The material is really nice and the plum is a beautiful color.
