Half the heddles are knit. I have a lot of obligations in the next 24 hours or so, so I'm not sure I'm going to get much more progress made before Wednesday. But I'm happy with my progress so far. The linen I chose to knit the heddles with is cooperating well, and the heddles are mostly very even. When you have to knit more than 800 heddles, you want a lot of consistency.
I am using the split heddle rod approach. Instead of one long heddle rod that goes across the whole six feet of warp, I'm using two, one on each half of the warp. I'm a little dubious about this approach since it's only a theoretical rather than a documentable approach. Still, it makes more sense than trying to operate a two-person sized warp and heddle rod all by myself without brackets, heddle rod supports, or anything else to hold the rod. From my experience weaving tabby on the Icelandic loom, though, I know it is possible to operate the heddle rod of a narrow warp one-handed while using the sword to secure the shed. I have tested and yes, I can move the current three-foot heddle rod one-handed. What a relief! I was afraid there'd be too much counterweight on the rod for it to be comfortable.
The fiddly part will be at the center of the warp, where the ends of the two heddle rods might overlap or bash one another. I'm solving that by making the dexter side's rod higher than the sinister side's rod.
Once the loom is entirely ready to weave, I'll post a full photo.
