Check out this awesome knitting/political action blog: microRevolt. Be sure to try the knitPro software that was developed by activist and site creater Cat Mazza. It will take a graphic and convert it into a knitting grid pattern. Try it while it's free, cause you can bet that this will be a hot item soon! Cat Mazza is an activist against sweatshop labor, which is a cause I can strongly identify with. See the Etsy interview with her, as well as some great resources about her cause.
