Bonnie Hunter with Quiltville has a lot of free patterns on her website, plus quite a few books (ask me how I know?) that you can use up a ton of those scraps!! Another thing, Judy Niemeyer has some patterns that call for 2 1/2 inch strips, like Weeping Willow quilt and Willow bedrunner, plus some of her other patterns. If it were me, I'd sort the scraps into light, medium and dark so they will be ready for use.
