She's elected to add two borders to one of them. It was assembled from blocks made from the project guidelines, all with red centres. However, because we had such a large stash of blocks, I was able to pull out 48, all of which had one or more green strings in them.
Since then, I've started (and now almost finished) another quilt top where all the blocks have red centre strips and at least one yellow strip in them. I'm expecting to have it finished in the next few days, and will post a photo.
