I started quilting back when lots of things (not just reds) ran and there was more of a problem with shrinkage. Since I like my quilts scrappy I mix my new and old fabrics for almost all of my quilts. I pre-wash all of my new yardage as soon as it gets in the door, even fat quarters, so that I know all of my fabrics have been washed before I pull them out to use them. What can I say? It's just the way I was raised.
