I always have a lot of long skinny scraps from the clean up cut on my batiks. One day I just sewed a bunch together and then sliced them off into irregular shaped strips. I had 2 sets that I was working from and kept flipping them end to end so the colors didn't line up all the time. Again, my favorite border fabric is some kind of a zebra print. I used Jane Sassaman's dotted fabric for the alternate bars.
