I separated the gorgeous skein of Handkerchief Trick into the 10 shades of blue that came out of it. Using Excel to map out the draft into color blocks, I worked out a color repetition scheme of 9, 3, 9 across. Each diamond is centered over the group of 3 threads, so this warp pattern yields diamonds that span three shades of blue each. This ended up being a fairly helpful strategy to work out the warping as I knew that each repeat had to be centered around the middle thread of the 3 strands of blue. Knowing where all the centers should be made it easier to keep track of each pattern repeat. I’ve attached the Excel image I worked out as I think it might be more helpful explanation of what I tried to do- though note that I ended up using a white weft rather than a brown weft.
Here is a link to some information on the diamond twill patterning that I really wish I’d read before warping. It would have saved me a lot of hassle from incorrectly direct warping the loom. Keep in mind that it end up being 1.5 x dpi of the heddle you use. I used a 10-dent heddle, so had 15 ends per inch.
Overall, I loved weaving this! It was incredibly satisfying to watch the diamonds emerge so it seemed to weave up very quickly. The next time I use this draft, though, I will use floating selvedges. My edges came out a little wonky.
