After meeting with Maria on Monday, I've decided to use all three of the fabrics for the final borders. I made more triangle pieces and sewed them into the border fabrics.
But, I trashed the loud corner blocks. I had the idea to replicate the rectanges from the center block. I made them as far as I could. But, the only Kona Zucchini fabric I have left is in small pieces. So, I'm going to think about what to do about that for now.
