You could make just about any quilt patterns with those 3 colors because they're so contrasty to each other (you'd have to want that effect, of course). Here's one baby quilt I made with some very simple blocks: (bottom right, showing front and back) But a friend in a quilt group of mine once made a sampler quilt only from reds, black, and white (mostly patterned fabrics though, not solids), and it was fabulous! The Turning Twenty pattern is a little unstructured to know where to use the different colors though, but this book shows at least one possibility: You might want to consider a pattern with a more regular pattern (all over, or in each block) so you could more easily decide which pieces should be which colors rather than so random.
