Finished with Week 1, the half arsed version. Decided to to take the number of units for the full quilt, if odd round up, divided by 2, if even round up again! For my colors, my grey is blue ("grey skies make me feel blue") and my gold is butter ("gold buys huns and butter"). My other color substitutions are much more dramatic.
Half square triangles as the first unit really keeps this mysterious.
As early as 1704, the Royal Academy of Sciences in Paris published a paper based on the work of a French Monk previewing the infinite number of design possibilities when using squares which are half light and half dark. A quilter named Jane Warnick created an "Element Key" based on this initial study showing the 256 possibilities for 4 half square triangles arranged in a square. Warnick's Element Key was published by Barbara Johannah in 1987.*
