The colour of the warp is something I would definitely do again - but I should have dyed some weft before I started weaving. I ended up using undyed silk hiro. It's an ok look, but not what I wanted.
I used a threading called Gothic Cross. I started out doing the suggested treadling, but then I started to do some variations. I think it looks pretty neat and am going to definitely use it on the actual scarves.
It shrunk about 30%, so I've redone my warp calculation and should be fine. Fingers crossed!
