I loved this quilt so much that when Jo came out with the pattern, I bought the same jelly rolls to make one just like it. Well, just like it *except* I kept the blocks all going the same direction.
If you look at the picture of the full quilt on the last page, you will see that there are blocks on the bottom right that are twisted! The chains are then broken.
If you do a search on Pinterest, there are several that come up.
I think it'd work great scrappy, as long as the chains are a consistent color that is strong enough to stand out as a chain.
