Constraining ourselves un-necessarily, are we?

No linear thinking required; just do a different grouping of tiles, individual unrelated ones, experimental ones, ridiculous ones. The point is any "logjam" is purely of your own making by adhering to that old notion these have to follow one after the other or be pre-conceived to "fit" somehow.

It's the whole point of the method; brainstorming now, storyboarding later.

As far as the Black Dog, they always pass with me, so I wish the same for you!
