Red Scarf complete.
Mistake rib, one entire skein of Caron Simply Soft (machine washable, non-itchy). Anyway, I could not believe how much yarn mistake rib eats up. I had about 6 inches of yarn left. Amazing.
The scarf is not exactly 60" long as requested, more like 55, but that's all the yarn I had and I tried it on, it's sufficiently long for wrapping and muffling.
This was truly a labor of love. My dad was an orphan and bounced around to various relatives. This scarf took me forever, but I wanted the perfect reversible pattern, that was stretchy and comfortable and it came out just how I imagined--manly but still red.
