Knit and Crochet to Save the World!
While I'm sure I can whip up a few dozen myself between now and February 2011 when this season's campaign ends, together we can give a great deal more. Free patterns are available at http://www.goodgoes.org/caps. Full details are on Save the Children's website. For those pros out there who dare not use another's pattern, all caps are to have a 12" circumference.
