Remember a while back, when I did a blog post about Kiva? Kiva is an organization that facilitates microloans: you use your Paypal account to lend money to a small business in the developing world. Kiva vets the entrepreneurs, then through their website, they connect entrepreneurs with lenders. You can pick the amount you donate, and it can be a small or large amount, depending on your resources.
When I first heard about Kiva, I searched their pool of entrepreneurs looking for knitting or fiber-related business. At the time, an influx of publicity had resulted in Kiva not having any entrepreneurs to fund -- they'd all been funded. But someone on Ravelry drew my attention to this group, a Bolivian collective that creates knitted sweaters, scarves and other garments to sell. The group still needs lenders, so if you're so inclined, check it out.
