Meredith...it looks gorgeous!! I'm going to have to vote for using the colored fabric for the scallops. Are you using the exact same fabric for the scallop as you used for the between? It appears that some of them are different. To me, the pieced tris seem like blocks and the betweens look like cones, so it makes sense to make the cone "complete"...I know, its silly...but... thats JMHO...
