It's been a long time since an act of craftivism has thoroughly gripped me. Check out The Gay Sweater, made from the donated hair of over a hundred gay people. As the group that made it says on their website:
The Gay Sweater project teaches us that words like ‘gay’ shouldn’t be used to describe anything negative. Please help the Canadian Centre for Gender & Sexual Diversity in continuing initiatives like these that work to eliminate bullying, homophobia, transphobia, and other forms of discrimination in schools and youth communities.
After you watch this video, be sure to click on the one about why they made the sweater. Oh, and watch the one featuring the knitters, too, which looks to have been filmed at the awesome yarn store Lettuce Knit in Toronto.
