My granddaughter's BF knits. He has a job that requires him to be alone and on call for periods of inactivity, then spring into action for a short while. He found that trying to read while waiting for the phone to ring meant that he lost his train of thought after the bell rang and had to start at the beginning when coming back. But he can pick the knitting up every time with no problem, and he ends up with something tangible that he is proud of.
