The best thing I have found for skunk smell is tomato juice. When my dogs get into a skunk I take them directly to the bath & bathe them several times with tomato juice. Rub it in really good & them shampoo them with a combination of the juice & soap. I've never had it on a quilt but I'm assuming you could wash it (or let it soak in tomato juice) several times. At times I've not had the juice so used tomato sauce, or ketsup....anything with tomatoes. Good luck!
