That's like the scarf I just finished, only on 8 shafts instead of 4. :)
Yeah, the reason I expanded it was I have 8 shafts. So now I don't have to remove 4. :) I will probably weave 2 or 3 strips as a time with additional shuttles. 2" is pretty narrow on a big floor loom. ;)
If you have this threading on an 8-shaft loom, you can weave it using an 8-shaft twill tie-up. Then it would really be an 8-shaft herringbone instead of a 4-shaft (2/2 tie-up) cloth woven on an 8-shaft loom. This kind of twill has lots of names besides herringbone.
