There are many quilt patterns that "start" with a 9 patch. One of my favorites is 6" 9 patch blocks with a triple sashing (3 one inch strips) and a small 3" 9 patch for cornerstones. I've made this in scrappy purples, scrappy teals and I'm making another in scrappy greens. It's a good way to use up my scrap squares and strips! Also, 9-patch blocks look great alternated with other blocks, either a square cut from one fabric or another pieced block like a star block or something.
