The funny thing about knitting is how little things can make a huge difference in the ease of knitting and in the look of a finished project. One of the most under-utilized and misunderstood techniques is the simple i-cord, or idiot cord - a tube of 3 stitches that can be used on its own or applied to a garment in a variety of ways. I've given you a couple of examples, but if you would like to see i-cord used to its full potential you can refer to some of the projects in Elizabeth Zimmermann's book Knitting Around. Better yet, watch the Knitting Glossary DVD where she gives no less than 15 useful ways to use this magical tube of knitting.
