I don't see how the picture is a 3x4 layout. I see across: a 4 patch of large rails, then a sixteen patch of small rails, then a 4 patch of large rails, then a sixteen patch of small rails. Going down I see: 4 patch of large rails, 16 patch of small, 4 patch of large, 16 patch of small, 4 patch of large, then 16 patch of small rails. How are we looking at it differently?
