Yellow Brick Road is a *great* pattern--for scraps, for fat quarters, for doing a fairly quick quilt that is very interesting to look at. I think it is one of the best patterns I have ever bought, for the ideas, for the versatility of it. And, I think you could use your 15 fat quarters (I don't know how many blocks that would make); but if you have 5 light fabrics, 5 medium, and 5 darker ones; or 5 large print, 5 medium print, 5 small print; or that the 15 fat quarters are balanced in some fashion; then you should have an interesting and successful quilt.
