In studying Erica's Magic-Step Towels draft, I learned the following. (This is exactly the kind of wordy writing about weaving I loathe, but unless I write this, I can't even tell if I am not understanding something. And it's weird for me but I'm going to read the draft threading from left to right, as yo use it in the linked draft.)
You have two choices in the threading:
(Consider the two threads in red a convenient spacer so the sub-blocks appear identical. But if you want to weave anything, consider carefully where these go, as I haven't figured out yet, but they probably go between blocks, rather than inside. Or not??)
Changes of warp colors coincide with changes of the shaft, and Erica started with the dark thread:
Woven as drawn in, it's easy to see we have a choice of 2x1, or two block, a vertical and a horizontal "stripes", with lighter color always coming from either the top or the right of each square in the draft, or the bottom and or the right in the cloth.)
But the walnut husk dye should be finished.
