Are you ready for this? It’s tricky.. Seriously, pretty hardcore.
280ish yards of a thick worsted, or even a bulky yarn, suited to size 10ish needles
Size 10ish needles
Cast on 48 stitches in whatever cast on method works for you.
Row 1: *knit, purl* repeat to end. Turn.
Row 2: *purl, knit* repeat to end. Turn.
Repeat rows 1 and 2 until you run out of yarn, leaving a couple feet to seam the ends together. You can whip stitch the ends together, or get fancy and do a kitchener stitch. I gave my scarf a single twist before seaming the ends together, and that gave it a great shape.
If you are a seasoned knitter, you are chuckling at my “pattern”, because it’s nothing more than a seed stitch. If you a novice knitter, you now know how to make a seed stitch. Basically you are just knitting into purl stitches, and purling into knit stitches. This creates an awesome and warm bumpy material.
Here are some great links to walk you through this.
I strongly recommend using the continental method, as the switching from knit to purl is much faster and smoother with this method. The KnittingHelp.com site is the site I used to learn to knit years ago. It’s videos are fantastic and easy to follow.
