It’s finished! I am really happy with this finished scarf. There was just barely enough black yarn in my stash to add 2 rows of single crochet to the ends. Once I finished with those I decided not to do the crab stitch border. If there had been enough of the black left I think I would have added it, but I didn’t want to use that bright green or bring in some other new color.
Speaking of color, up close you can really see the difference in the two black yarns. Luckily, at a distance it is much harder to see. I feel justified in my decision to use my stash yarn, and I really like the way the finished scarf looks.
