I don't know for sure what the gingham that my aunt used in a beautiful quilt is for sure - but I believe that it is poly/cotton and I have washed/line dried that quilt dozens of times and it is as soft and smooth as the rest of the quilt. Also, the best set of sheets that I ever had were from KMart years ago and they were a blend and just got softer with every wash and dryer load. HTH
