I worked at Joann's for many years and know this: the coupons and various discounts depend on the cashier only, unless he/she asks the manager(they rarely ask because managers consider cashiers too "low on the totem pole" to bother with.) Thread is in the notions section at all Joann's I know of, though it's often on sale when regular notions are not. Up to the cashier. Raise a little stink and they'll honor those specific-department coupons.
