Infiknit is a needlework kit and pattern distributor with an inventory of over 1000 patterns created by more than 40 designers from 3 countries: Canada, the United States and Britain.
One cool product they have is EcoKnit Yarn - 100% organic coloured cotton yarn. It’s apparently great for knitting (I haven't tried it myself yet) and great for the environment - the cultivation of cotton is said to account for 24% of world pesticide use.
Here are the yarny details in yarny-speak: 100% certified organic cotton grown in colors, 20 to 22st to 4in on 3.5 to 4.5mm needles. Deliciously soft lustrous yarn in 50g, 100yd skeins. Bagged 10 to a bag for stores. : Here's the link
