Maybe this is why it has taken me so long to finish "My Shetland Shawl". I got bored with it and needed to do some mindless knitting. Mindless knitting is something you can work on while watching TV, chatting over coffee, reading blogs or driving. If you're knitting and driving you have to push your seat waaay back so your feet will comfortably reach the steering wheel. It also helps if you remove your footwear.
Knitting doesn't get much more mindless than this.
