Just cruised over to the Quilt-in-a-Day site. They have notions, rulers, by-the-yard fabrics and fat quarter bundles among their sale items at fair prices on a regular basis. Even after shipping, some are well within the range of WM prices.

not quite as much fun as going nuts in person at a fabric store, but I'd expect we can trust Eleanor Burns for quality.
