gaigai, your blocks are so beautiful. :D
You were wondering about the layout and as I was looking at them, you definitely seem to have three colorways working. I was wondering if you put them into a snailtrail-like configuration if that would work what with the reds, the greens, and the blues? Kind of like the infinity symbol only with 3 spirals instead of two. Just a simple suggestion.
They will be lovely and anyone who receives them will be pleased! :D
