There is cotton broadcloth and poly/cotton broadcloth. I bought some broadcloth with 100% cotton printed on it and when the iron hit it, it was like watching shrinky-dinks. Never had that happen before or since but I will be on the look-out in the future and iron test it before using it. I have used broadcloth in some children's dragger quilt as it doesn't fade and washes up beautifully.
