For crafty upcyclers, knitting is a handy tool. Got an ugly holiday sweater? Vent your anger by ripping it apart — and reknitting it into something cute. Reknitting pre-loved yarn is one of my hobbies — a creative challenge that keeps my knitting green, too.

Upcycled yarn, in fact, is one of the many sustainable knitting options highlighted in Knitting Green: Conversations and Planet Friendly Projects, a new book by former Knits magazine senior editor Ann Budd. This eco-educational book highlights eco-friendly yarns from organic cotton to silky soy — with patterns for knitting projects using these yarns, complete with photos showcasing how good sustainable knitting can look.

In Knitting Green, would-be eco-DIYers are first given a rundown of the environmental issues associated with knitting — because while the human-powered act of knitting itself is an eco-friendly endeavor, the process of creating yarn is often not. For eco-fashionistas with some knowledge of sustainable fibers, many of the green knitting issues Ann brings up will be familiar. Conventional cotton is grown with a lot of pesticides, bamboo yarn is processed with noxious chemicals, and wool poses animal rights and chemical pesticide issues. And that’s even before the yarn gets dunked in un-green dyes and shipped half way across the world!

Knitting Green goes into solutions, highlighting eco-friendlier choices people can knit together using the many new greener yarns now on the market. Patterns range from the Back-to-Nature Hat made with organic O-Wool, an all-North-American hoodie made with wool that’s grown, harvested, and processed, in the U.S — and for the really crunchy knitters, soap nut vessels for the laundry, knit with hemp yarn.

The patterns I wanted to knit up were the accessories, like simple and functional socks and slippers I could wear around the house. My favorite pattern is the Paris Recycled Scarf (right). The “yarn” comes from lightweight silk fabric, sliced up!
