RyanGi - Thank you as always. Maybe the checkering is only in the small area and asymmetric because I was too scared to make a mistake... who knows, haha.
LBD - Thanks for the thumb upS. Yeah, I've seen a 3x3 (1 single piece to lock) or 5x5 (2 pieces to lock) puzzle out of it and you can make it but be sure to make it a loose fit or once all joints lock in place, you can't release them.
Dave - Thank you. I was being sure not to skip a single line but I still need a lot of practice!
