Hi Rich,
Here are a few more images to digest, including one of the waq-waq motifs.
You correctly note that each selvage cord has more than one warp; looks like two, to me. Along the side edges of the pile, I didn't really notice anything out of the ordinary, structurally.
The knotting is symmetrical at all locations; no switching at the edges. And I find no evidence of offset knotting either; the weaver opted for high resolution instead, so all the curves are non-offset knots.
Looking between the knots, the weft tensions do not look intentionally variable. There is a little warp depression, but it appears to be almost random and not particularly strong. It shouldn't be too variable along a single knot line, yet, it is. The somewhat puckered look you also correctly note, seems to be more from tying knots tightly, to very tightly, but somewhat variable long a line.
The handle is floppy and the rug is heavier than you might expect given the thickness
Regards
Chuck
