It's really cold here in the Bay Area (and looks like it will be still chilly for the rest of the week). The Procragratification Scarf is a fast, easy infinity scarf pattern that will definitely keep you warm during this cold spell.
This pattern uses the fisherman's rib stitch pattern, which requires you to knit and/or purl into the stitch below. I was asked a few weeks ago about how to knit this particular stitch. I thought I'd post this video tutorial that I found on YouTube which does a great job of showing how to work this stitch pattern.

The Purl Bee, one of my favorite knitting websites, also has a photo tutorial of how to work this particular stitch, with two accompanying patterns for a scarf and cowl here. Enjoy and stay warm!!
PS:If you aren't a knitter, I have these chunky, ultra-warm infinity scarves for sale in my Etsy shop!
