I discovered the bow tie while working out some stripes that will appear in future squares. While making it, I noticed that even though the center 'knot' stays the same size, the design overall scales quite nicely.
While the square above and the pattern are 19 rounds, a smaller square reads just as clearly. I dressed this 13-round square up even more with sparkling metallic beads and a 3-color 'tweed' background. It would work in a wide variety of color combinations, too.
