Colour co-ordinate and fibre match your knitting to your outfit. You will look so put together.
Don't watch The Day After Tomorrow when it's -38*C/-34.6*F and you are sitting in a draft, also known as your living room. You will be planning how you are going survive the new ice age all night and in the morning at work, when someone calls with a basic question that a chicken with it's head cut off could answer, you will have to call them back. After you look it up and or ask someone because you couldn't think where to look it up.
