So quick on the replies! I am amazed! Also on this (is the quilt patrol reading) I did it with batiks and NO I didn't pre-wash. A drop of water got on one of the blocks after it was put together and yes as the quilt law goes it ran. I have used the color catchers before with other stuff and it helped but I have never used the quilt wash stuff. Does it keep colors from running? On one of the old timey calendar it says to put black pepper in the final rinse water. Hummmmm LOL Robin
