Columnar Jointing is a simple ribbed beanie—or is it?

(It’s not. Well it is. Sort of. It’s both simple and not too simple.)

But it features an unusual construction, which makes it much more interesting to knit, while resulting in a hat that’s well-suited to a minimalist or masculine style sense. I like knitting weird hats (see also: Driggs), but I like wearing plain ones, and this one satisfies both preferences pretty neatly in one simple hat.

Materials:
About 130-168 yards of Malabrigo Yarn Rios, or similar worsted-weight yarn
1 16” circular needle and 1 set of DPNs in US7-8/4.5-5.0mm, or size needed for gauge
4 stitch markers
Tapestry needle

Gauge:
Gauge is 20 sts and 24 rows over 4” of 1x1 knit-purl ribbing in worsted-weight yarn. This measurement is flat and without tension—ribbing is stretchy! Please be sure to check your gauge.

Specific Skills:
It helps to be familiar with or comfortable slipping stitches and picking up stitches, and working in the round, but if you can knit and purl and are determined, you can knit this beanie. (It’s probably not a great first project, though. A little experience will help the shaping make sense.)
