Pattern: Twisted Rib Neckwarmer (rav)
Yarn: Malabrigo Silky, color 429 cape cod gray, 2 skeins (every single inch of two skeins)
Needles: US 7
This is a nice, soft loop that you can wrap around your neck twice. I ran out of yarn at the end (trying to make just one more twisted repeat) and had to use scraps from my long tail cast-on. Even then, I had to kind of fudge the bind off. Oh well, it's not noticeable when I'm wearing it.
The single-ply yarn is just right for this pattern:
The only problem is that this project got tedious real fast. Oh em gee. For real. I thought it was called an infinity scarf because you twist it into a figure eight to wear but really, it's because the rows feel like they take forever.
