Happy Summer-ween! You can certainly wear this Natural Summer witch hat all year, but it is specifically designed with Spring and Summer in mind! I chose to make this from a hemp cord so it would be airy and ultra lightweight, but still easy to shape. I crocheted the brim in a hand dyed merino and gave it a loose stitch for ventilation on those hot days. The suede cord ties are easily adjusted with a push or pull on the bead, and are attached with a simple slip knot so they can be removed if desired. Firm enough to stand on its own, comfortable to wear. Airy enough to get through the heat and folds flat for travel.
