Oh, OK, wefts.
On mine the wefts are two shots of medium brown wool, both very loosely twisted. Knotting is asymmetric.
I will be interested to see if Joel has anything to say; he focuses on Baluch work.
While on the topic of balishts, take a look at this one, which I found several years ago. I assume it is Baluch.
The knots are symmetrical, making me think this is from eastern Persia somewhere. Warp and weft are ivory wool. The selvage is made up with 4 cords, with variable colored wool and hair wrapping. Some of the orange is tip-faded. It has a few pale blue silk knots in some of the white gul center detail. I like the white ground panel at the bottom:
