Your quilt is VERY Pretty.
I have never used the blue and have decided not to, but have used the yellow "ONCE! The yellow never came out after several washings. I thought maybe it was because it was on white, I honestly don't know. I've never used it again for that reason, and probably won't until find something to get it out or why it won't. It hasn't been ironed. I have used the white chaco and have never had a problem. hmmm.... I will finish reading this thread and watching for any ideas to remove it.
