It seems counter intuitive for a company that sells clothes to sponsor and event to repair clothes, but that is just what is happening at Patagonia. Even more surprising: they are going directly to the consumers to make it happen.
Patagonia is sponsoring a Worn Wear Tour, taking a van to colleges throughout the country and repairing clothes (of any brand) to keep them out of the landfill. No selling involved; just free repairs on articles of clothing, done in partnership with the Post-Landfill Action Network. You can watch a video about the process here.
How can your organization get involved in a project that does the right thing, even if it doesn't lead to direct sales? What service could you perform that may seem like it works against your business, but ultimately could enhance it? Is there a cause you believe in that you could promote, even if it doesn't have an explicit business link? Use Patagonia's Worn Wear Tour as a model for thinking outside the box (or store) to create a project that sews together your passions and service.
