Not exactly like your color placement,but it appears to be - from top left to right- square of one color - say 6 1/2"-cur-other blocks are strip (3 1/2" X 6 1/2", and two 3 1/2" squares- one of same color as strip, other same as first 61/2" square....then when sewing into rows, turning to make the "link look". That's how I would break it down....perhaps a quicker way, but just off the top of my head
