Part 3 of Ralph Griswold's crackle weave series explains designing with a 1,2,3,2 motif placed along a path. It defines path properties (connected, disconnected, friendly, unfriendly, extent) and shows how flats, friendly paths and disconnected paths affect the resulting drawdowns. It also covers float lengths, palindromic enhancement, modular reduction to fit a given number of shafts, and the very large number of possible paths to explore.
