I did have an idea while lying in bed this morning prior to getting up.
I want to do a big star block and surround it with tumbler blocks. I had to use EQ and Photoshop to get the idea going. Here is my mockup. I couldn't get the tumblers on the sides to look right just yet so I just threw in blank yellow area for now.
Not bad, but still not what I envisioned. At least now I have made a "note" for myself and can come back to it later.
