Personally ladies I salute you. I tried pre washing for a while and then color catchers came and I fell in love. If I had to pre wash I would never quilt again. I'm serious. As much as I love my quilting I would not go through that much work and end up with fabric that is not as nice. All the nice sizing is washed out, if you starch you draw bugs. That said, I only buy really good fabric. If you stick to the good brands Moda, Hoffman, Marcus Bros, etc, you won't get the shrinkage and the color catchers are super - I use 5-6 in a new quilt wash. I've not had a run or mismatched shrinkage.
That said if you are not comfortable with not washing, then do what you have to do to feel comfortable. I'd just rather sew than wash.
