The double weave yardage was cut off yesterday, washed, tumble dried, and scanned. You saw it on the loom here. Now here it is after finishing. The pink rayon weft cooperated well with my original plan, and shrank a lot more than the cotton and bamboo, and I've got a nice crinkly fabric. Front and back views follow (or is it back and front? It really doesn't matter with true double weave).
And here's a scan at about 12x magnification, so you can see all the little fibers and the structure (click to enlarge).
To summarize: the white warp is bamboo, the white weft mercerized cotton, the red weft unmercerized cotton, and the pink weft rayon. All yarns in the 20/2 to 16/2 range, and sett 40 epi. Networked plain double weave on an 8-end initial, hence the extreme sawtoothing (is that a word?).
Weaverly's about to set off on a journey, so you may not hear much from this station for a while. I'll try to post whenever possible; but until then, happy weaving all!
