While you are waiting for Spring, put it in one of those tote bags made by the freezer bag company. I think it is Zip Loc. In with the quilt put a few sheets of softner that you would use in the dryer with your laundry. They say that the sheets will take odors out of sneakers overnight so it should work on the quilt. I doubt there is anything in the dryer sheet that could possibly harm the quilt but you might want to read the ingredients on the box first.
