Personally I think tutoring is the way to go if you have the skills, I doubt you can get the amount of money from making anything that you can get from two hours of tutoring for example. One evening or Sat morning a week tutoring I think is also more achievable than trying to fit in other things around children. I have a friend who did all through her leave and she did well out if it and enjoyed the work. She also did exam marking but that was a bit more problematic as required a lot of time over a few weeks. There always seems to be more money in teaching someone else something even if is a craft thing/IT skill than creating items yourself - (which is a good thing really - people being prepared to invest in learning rather than items).
