2 stars because the color was a great bright yellow as advertised, they were very affordable and shipped fast. 
This is one of those you get what you pay for. If I had not had company arriving 2 days after I received theses, I would have returned; but circumstances had me use them instead. 
Firstly, the sewing was terrible; see pics. Next there were discolorations all over it; see pics. I tried washing, hoping it might come out. It did not wash out. They are slimy feeling, but very thin. I do not think they will last as everyday linen, but will work for guest bed I suppose. I would not buy these again.
