I must say when the package arrived, I was puzzled by the weightlessness of the sheet set.  I looked at the contents, they looked like a very nice damask.  I saw 1500 threads to the inch, and realized it was all pure polyester!  There is no weight to these sheets.  I expected something different.  I decided this wasn't what I expected or  wanted.  So, I am returning the package today.  Sorry, I should have realized that 1500 threads per sq. inch has to be pure polyester.  Thanks anyway.  

Cons: I saw some 500 thread sheet sets that were very pretty, the price was a little more, but the sheets were beautiful.  However, the color I wanted wasn't available.  So I am still looking.
