It took using someone else’s camera, but I was finally able to get a picture of That 70s Scarf with reasonably accurate colors.
I have since woven in the ends and finished it off. Haven’t blocked it, though; been wearing it “raw” so to speak.
This was Yet Another Color Block Garter Stitch Scarf, in various shades of Cascade 220 that I happened to have on hand. It pleases me greatly.
