The Houndstooth Slouch hat is one of my first published patterns (December 2016). It uses and extra stretchy slip stitch brim, combined with some simple color work to create a houndstooth effect. You will need two colors of worsted weight yarn to make this hat. This hat is currently written in adult size, but could be easily modified for childrens sizes.

You can find this pattern free on my blog.

This pattern was updated in October 2020 include new features including sizes Newborn - Adult, new brim technique, and a decrease section to shape the beanie.
