Should I ever make a quilt for sale, I would absolutely wash it before selling. I use a lot of "crap" putting my quilts together, like I said in the baby quilt thread. People have so many different sensitivities, at least if I wash it in a scent and dye free detergent, whoever is getting my quilt (whether it's a gift or a purchase) is wrapping up with a minimized risk of irritants. I do (and will) tell my quilt recipients that I did launder the quilt using "this" detergent, these are the washing instructions for reference.
