Thinking of making the horns and the arrows on the bottom of the straps out of red yarn.
Might do that with the Artesano 100% Alpaca 4Ply in red that I have left lying around.
I did end up doing that, holding four strands of the yarn. Absolutely in love with how that worked out!

Finished knitting the black part of the hat on Feb 26^th, on to the hearts/arrows/devil’s tail ends on the bottom of the ties and the horns.
