Gerbie, LQS is "local quilt shop". Synthrapol is a liquid and you add it to the wash with the quilt. It is supposed to suspend/remove excess dye, so perhaps it would help. It is 1 teaspoon for each yard of fabric. I just estimated. It says to wash in hot water, but I did it in warm. It also says to wash the material in it to set the colors first. Well unfortunately I didn't. But my quilt did come out ok.
Someone on this quilt said that what I did was the wrong thing, so you might want to start a new topic and ask for advice from some of the ladies that are more experienced with this. Good luck.
Amazon.com has it. Maybe you could get the shout color grabber sheets at your local WalMart.
