I just finished ironing 17 yards of the red I bought today. I washed it 4 times before the rinse water was clear. I also used hot water to make sure it shrank all that it is going to. I found that if I put washing soda in the wash water, more of the dye came out. But that's OK. I just don't want anything to happen after the quilt is made, no matter how it is washed. I bought so many yards [the entire bolt again] as I had another 60% coupon and I ended up paying just over $1.10/yd. I'm going to use the rest of the yardage for the backing. I think I'll wash all of the muslin tomorrow and see how that shrinks.
