Whats your preferred noise to knit to?
I dont have my tv on much so i go for music.
Serge Gainsborough mostly but, Nick Cave, Travis, Jarvis Cocker and Patrick Wolf also work for me.
I dont know why but Gainsborough is just perfect. Its all relaxing but entertains the ears without distracting. but careful he might convince you of knitting one of these http://www.themillenniummall.net/muff.html
