microRevolt is a knitting project targeted against brands that use sweatshop labour. They aim to get the message out by knitting garments with the offending companies' signature logos and their latest project was a petition against Nike, where petitioners would send in hand-knitted squares to represent their signatures. The squares where attached together to produce a 14-foot knit banner of the Nike swoosh. The banner was then presented to Nike Chairman, Phil Knight.
