Yes, Patchwork Puzzle is my #2, Greg - and probably should be my #1 because it is accessible, since it's been introduced! (Maybe seedlings shouldn't count? Will we ever have a chance to buy it?)
Please post a picture of your favorite.
That seedling of Kent's is gorgeous!
Let's not get tooooo serious about this. It's a game. Which one makes you catch your breath? The most? Today. Post a picture of it.
