Is it really possible to apply CS skills to all hobbies? If yes then how do you apply CS to hobbies like woodworking or crochet? The only thing I can think of is a retail site, but then again why wouldn't you just use something like tindie?

Or should people who don't do coding related hobbies not do CS? Which is a special requirement just for this major. People in civil or biomedical engineering don't apply their majors to their hobbies.
