My grandmother made crotched pineapple design double bed coverlets for each of her children when they got married. My mother never used it and gave it to me long after my father had passed. I decided to save it and placed it in my hope chest. Now eighty plus year's later, I would like to use it in my craft room, but don't know how to get the rid of the smell. Should I gently wash it and hang dry or take it to the dry cleaners to see if they can help?
