It's always interesting talking with customers, hearing them attempt to restrain themselves from starting new projects or trying to rationalize their yarn purchases. They sometimes feel guilty about their passion for colour, for texture, for design and for yarn therapy.
There are knitters, believe it or not, who insist that they can only have one project on the needles at a time. Others don't start to worry until they have more than ten works in progress. I recently talked with a quilter who had 27 quilts-to-be stashed in her closet. She was at a knitting class :)
I believe that multiple projects are the rational way to knit:
Can you imagine spending a month where you limited yourself to watching only "Leave it to Beaver" reruns? The next month, you watched the Nature Channel and the next month, only the "news".
Or how about reading? Could you really read "War and Peace" every day without spending a few minutes with the newspaper ...or a knitting magazine or book?
We all know that some knitting projects require the focus of "War and Peace" while others are more like watching the Beav. Life, and our minds, are like that. Sometimes we need a challenge and sometimes we don't. When you have variety in your knitting bag(s), you are ready for any knitting occasion ...and no potential knitting time is wasted!
