I can't date any of the fabrics. I have heard the poly/cotton used for blouses and dresses will not fade nor wear as fast as 100% cotton and therefore they shouldn't be mixed. However this quilt looks great. Ask your Daughter not to wash it too often, washing too often hurries the wearing of any quilt or comforter. Sorry, I can't help dating the fabrics. It is very pretty and she is so lucky to have it.
