This pdf includes the basic strappy Haka hat (simple, super quick, and great for beginners!), the cabled Haka hat (also quick in bulky yarn), and the matching cabled cowl!
Use super bulky weight yarn, or 3 strands of worsted weight held together, or any other combo that will get you 2.5 stitches per inch. All projects use a 16” circular needle, size US 13 or 15, to get gauge.
