I've used coupons and collected packages of W & N for a few years now. I cut up several of my deceased brothers' all cotton, button down, business shirts. Our local quilt guild has a "Mall in the Hall" sale twice a year. After 7PM items are discounted 50%. Absolutely hit the sale bolts at the LQS. For backing I will use Cuddl Dud flannel sheets, around Thanksgiving they can be bought at Kohls for a great price.
