Prewashing large cuts of fabric?
I know I read a thread about this before but have not been able to find it. I am about to start a couple large sized quilts and the fabric is all over 3 yards of each piece. How do you wash these to stop the twisting and knotting? I have washed up to 3 yards but I always end up with strings that bind around the center of fabric. Any tips would be appreciated!
