Krampus season calls for this amazing horned head covering

Regina Weiss of the blog Morale Fiber upped her Krampus game this year with this amazing hand-crocheted hat. Even its horns are made of yarn.

Get the pattern for free on her site or support her efforts by grabbing the pdf version for $5.50 at her Etsy shop.
