I've made a simple block for the center of my liberated round robin quilt by taking an old 9-patch and adding the blue scraps to the corners. But some of the blues weren't large enough, so I added the burgundy. Then came the slash and two black fabrics from my scrap bin.
the block is 6.5" x 6.5" so my quilt won't be too large.
