I had 93 g of this yarn (243 yards) for my handspun version of this super-simple design. On the 7s, I was getting about 6 st/inch in the 1x1 rib, so cast on 36 for a 6 in wide scarf. It ended up being about 5 inches wide, but is a great, thick, flat, soft soft soft fabric.
This project has a special place in my heart because I cast on during my last day of grad school and finished it during the last day of grad school symposium. I wove those special memories into the scarf.
I typed up the pattern to share.
