I just made a chevron quilt top with white fabric and a single red, white and blue fabric. It was quick and easy, and looks great. Haven't take a picture of it yet or I would post it - it's in the garage and it's too cold for me to go out there now. I'll try to remember to post it tomorrow.
The r,w,b fabric was a stripe, so it gave the quilt a kind of scrappy look without being scrappy.
Here's a link to a tutorial that shows the method I used to make the 1/4 square triangles. I used 9-7/8th inch squares which made a large enough 1.4 square triangle to make the quilt go together quickly.
