This pattern collection completely sets you up for a toasty warm Autumn. Using just about every inch of one hank of Fourth of July will give you the complete set: a short pair of wristers, slouch hat and cowl.

Or you have the option to cut one of those choices out to make longer wristers or a super slouchy hat…or perhaps you still manage all 3 with a much smaller cowl. It’s a “choose your own adventure” of fibery goodness.

The wristers are crocheted flat,then seamed. The hat band is worked flat, then stiches are picked up along the side to begin working in the round. The cowl is worked as one continuous circular piece.
