OK, I'm convinced. I'll take my quilts out of plastic. I don't use dryer sheets, but I do put a cedar ball in a double layer of tissue paper and put it in with my quilts etc. My SIL is allergic to fabreze so I can't use it. I'm allergic to just about everything scented (except cedar) so I am very careful. I think I'll try good ole Ivory soap; I used to shower with it so I guess it will keep quilts smelling fresh without setting the allergies off.
And as a former smoker I can vouch that smoke gets into everything, even the most remote corners of your house.
