A book I currently have on loan from the Public Library is "Knitting Without Tears" by Elizabeth Zimmermann. This brings me to my first reason that knitting is good: You can enjoy passages such as the following, even when you are not knitting.
"Decide on the width of your sweater. There is no set rule for this as bodies and tastes in fit vary enormously. Pay no attention to your "size," be it size 7, you enviable creature, or 54 1/2. The important thing is the body-width you want, and the best way to ascertain this is to lay your favorite sweater out flat, and measure it. Multiply the number of inches around by your guage (see Chapter 2), and the result is the number of stitches to cast on for the sweater body. This is almost the only measuring and deciding you will have to do for yourself (after all, no one can do it for you), and it is important to do it accurately and conscientiously. Otherwise you may sup the porridge of regret with the spoon of sorrow."Wonderful, isn't it? So informative, and yet so subtly hilarious. I can't wait to make my first seamless yoke sweater using the techniques put forth by the self-described "opinionated knitter," Elizabeth Zimmermann.
