Sew the one of the shorter of the four units we just made to the left
side of a Color 2 larger square, pressing seam out towards the pieced
strip. Sew a longer pieced unit to the top, again pressing seam out
towards the pieced strip. Make two units like this...
Now sew the four completed units together to make the block,
pressing row seams in alternating directions!
Here are four blocks by four...note that the
construction of the four quadrants of some blocks is reversed...:o)
