The Ocanom Bulc hat is worked in an unusual stitch pattern with an amazing cushy texture. The original hat uses only two colors, but what keeps you from adding a third?
Here are the adapted pattern instructions and charts in 3 colors for you to use creatively.

Some more info:
The original Ocanom Bulc hat was created by reverse engineering a factory knit hat. Difficult? Not so much as it may look. It’s all about one special stitch, the k4below a.k.a. a tuck stitch.
Once you’ve mastered that stitch, this hat is a lot of fun to knit. At least, if you don’t mind purling!

NB The tricolor version has nog yet been testknitted.
