Here are those calorimetry pics I promised. This was a gift from my organic farming, knitting, all-around cool friend, Zeb! Thanks Zeb! Pattern was mentioned on MDC's dread thread (that's mothering.com). It really worked well keeping my head and ears warm this winter. I tried hat after hat and none really fit well over all this hair..but the calorimetry....kept me toasty! He made me a blue one too, but winter was over before I got to wear it. Next year!
