She had bought her fabrric at a reputable quilt shop and was assured that all fabric was 100% cotton after 9 weeks of frustration the teacher suggested the burn test. One of the fabrics melted away definetly not cotton.I still can't understand this as I have put poly/cotton with cotton and had no problems but this particular fabric shrunk at the touch of an iron and distorted every block
I had some white on white that I did not pre-wash and it did the same thing. It looked just like other white on whites in my stash but it shrivelled terribly when ironed.
