This Christmas tree hat is worked in Brioche with scope for your own creativity, to give it a “decorated tree” look. All techniques are explained and the pattern is tested. In my opinion it is suitable for advanced knitters. Sizes range from Newborn to adult and the pattern includes Brioche decreases, syncopated stitches, and optional extras such as one line of cables in the brim for a tree trunk with a slight zig-zag edge, a crochet chain stitch for a trailing “light chain” and a pompom for the top.
