I tend to underestimate just how much longer it takes to thread the heddles when I have a wide, dense project. In this case I'm maxxing out my ~40" wide loom with a 12 ends per inch warp. I've now threaded 240 heddles, which means I'm halfway through.

@golemwire Heddles are the vertical metal bars the yarn threads through. It is a lot like threading a bunch of large needles. Depending on which harness the heddle is inside, when you press food pedals called "treadles" the yarn is lifted and sits above the perpendicular "weft" yarn you pass under it. The yarn that sits above vs. below defines patterns and colors in the fabric.
