Constructing these blocks I learned to choose a general layout carefully. For example, repeating rows of light, medium and dark is both boring to construct and dull to view. The blocks improved when the rows were more randomly placed.
I wanted a red/pink/orange main diagonal but found the intersection of those rows unappealing. So I alternated r/p/o on the longest and second longest rows.
Fret not; enjoy the day.
