This pattern is a simple combination of two stitches - knit stitch and slip stitch. All of the slip stitches are done purlwise with the yarn in the front. This combination creates a thick fabric with an interesting texture on both the right and the wrong sides. Because this hat doesn’t have a typical knit/purl brim there isn’t as much stretch as most beanies so it is really important to keep an eye on your gauge. FYI: Most test knitters have had to upsize their needle size to match gauge (for example I usually knit hats with a US5 but for this pattern I needed a US8 to make it work).

There is an alternative version of the hat which includes a brim - this gives you a little more flexibility in sizing, but I still recommend working up a gauge swatch.

In total the hat needs about 35-50y per stripe (as written 100y color A, 50y for each of the other colors).
