I finished up the blankets yesterday and after a few rows of stitching to stabilize each end I threw them in the washer and let it soak. 38" in the reed is now only about 33". The drape is really wonderful. The smooth warp spun yarn makes the blanket very soft right from the start, unlike some of my mill-end 8/2 blankets that needed a few trips through the wash/dry cycle.
Here's a close up of each of the four blankets.
Blue weft gives a zig-zag effect using this treadling.
One pick green, three picks blue with what I believe is called a straight draw.
This third blanket uses the alabaster (same as warp) for one pick and three blue picks. You probably don't need the draft but what the heck - I already uploaded it!
Finally, this uses one shuttle all the way through. While I'm not sure this is technically a "broken twill" it sure looks like it to me.
Tomorrow I'll cut them apart, hem them, wash them and give them a hard press. Wonder if they'll shrink any more?
