p. 22, "Hexagons"
from Knitting Nature:
While hexagons fit together perfectly in a flat plane, their six-sided geometry allows them to fit together in myriad other ways. Depending upon which edges you choose to join, they can form straight lines, curves, and waves. In this coat, the hexagons form their signature flat pattern in the background, then are joined end to end, like a string of pearls, to trim the neckline and create a long, flattering visual line.
