My current project. a red, white and blue. #1 is how the book had it laid out but I saw another way #2 that created some different shapes. It also has the advantage of being able to have odd number of blocks across while #1 needs to be an even number.
Layout #1 really needs to be an even number of blocks across

Layout #2 has a strong diagonal direction which could also go in the opposite way too.
