Christina, if I had to pick one traditional block and only make variations of it for the rest of my quilting career, I would pick a log cabin. I had a lot of fun making these blocks for you, and I hope they work with your vision for your quilt. They are both about 17" square, so hopefully there is enough wiggle room for you to square up as you desire.
I know that the navy Riley Blake print in the block on the right isn't the brightest, but I couldn't help myself. Hopefully when you see the little spaceship, it will remind you of me (Quilting Jetgirl). :) I am excited to see how your quilt top comes together!
