Graphic

Here's my plan:

 (A closer look)

 This tells me how big each rectangle is -- the numbers are the number of ridges each way. I don't know that I'll knit the entire graph. The green segment is the one I'm currently knitting.

Each rectangle is being knit as two triangles, knit in different directions, knit from different colorways.

The colorways allow themselves to be divided into the lighter and darker groups, so I alternate those as well.

One other variation that's emerged is that I'm doing one colorway by alternating two colors, and the other colorway knitting two ridges of each color. I love how these sorts of details emerge -- that's the heart of conditional knitting.
