Knitting and crocheting have experienced a renewed popularity as a new generation of crafters embrace their needles and yarn. As a knitter myself, I love heading to my local yarn store (LYS) to check out the beautiful multicolored skeins.

The big question for an eco-friendly knitter is this: what kinds of yarn leave the lightest footprint? Many knitters steer away from acrylic for various performance reasons, but synthetic yarns are also bad for the earth, since they are made from petroleum. Vegans object to using wool, and, although great for many heirloom projects, are just not as sustainable as some of the newer options. Industrially-produced cotton brings with it a slew of environmental problems, including water and soil pollution.

Until recently, my LYS only had earth-toned organic cotton, which was beautiful for a baby blanket, but didn't allow for enough variety for a range of projects. Is there anything else out there that will allow me to make awesome crafts in a greener way?

Fortunately, eco-friendly fibers have exploded in the past few months. Some, like the organic cotton, take an existing fiber and green it up. However, a whole new crop of yarns are being produced using normally cast-off materials. South West Trading Company, of Tempe, AZ, makes yarns and fibers from soy, corn, bamboo, even milk and shrimp and crab shell fibers. Their SoySilk fiber is created from byproducts of tofu production (and is produced in a variety of decidedly non-earth tone hues). Bamboo (which, because of it's rapid rate of growth, is a popular green knitting needle choice) produces a soft fiber often compared to silk or cashmere. Hemp yarn is also gaining popularity beyond the granola-set of knitters, and recycled silk, spun from old saris by women in Nepal, is a unique fiber to work with. Most of these yarns can be found at Yarn Market.

But why shop online? If your LYS doesn't stock green yarns, just ask. Most will stock it if people will request it. At the very least, they'll order it for you. After I bought up most of the organic cotton at my LYS (hey, it was a bigger blanket than I had planned) I was pleased to find that not only did my store start stocking a much wider variety of eco-friendly yarns, but they even sponsored an event to promote their new lines.
