This is called Sugarplum Stars. Have I gone star-crazy? Pattern is available free here. I think it would be great scrap quilt. I can see it (in my mind of course!) made in leftovers from various other projects.
This is called Blue Moon. The blue and white combination and simple graphic design is so crisp. It would be a good two-color design for scraps. You can find the free download for the pattern here.
This one is called Desert Nine-Patch; you can find the pattern here. It is made with Tonga batiks and two alternative background fabrics, which is what makes it special for me. I think you could make it with a Bali Pop, jelly roll, or strips from your stash. The key is to use the two backgrounds in alternatting blocks.
