This one looks easy, right? Well, ignorance (mine) is bliss because it is not!
Consider this: the entire block is 4.5″ (11.4 cm) square. This makes the center piece 1/4″ (0.60 cm) – does that raise the difficulty level just a tad?
The block looks a little wonky – that is mainly due to my photography skills (or lack thereof!)
This is block # 134
