Ironically, the calico version was harder to put together than the real thing will be. The beauty of the double weave structure for this design is that it eliminates all but two seams. I had to fiddle with the calico and my overlocker to make those non-existent seam sit as unobtrusively as possible.
My plan for today is to do as much as I can before it gets overwhelmingly hot again. I'd like to dye the mercerised cotton I'm going to be using as the warp for the real thing. There's enough warp left on the sample loom to try a couple of different approaches to closing off the bottom of the bag as well.
