The Society for Creative Anachronism encourages participants to dive into historical research and reenactment, and to share their knowledge with others. You will find singers, storytellers and dancers, calligraphers and painters, tailors and milliners, leather workers and armourers amongst our people. Any craft that may have been utilized pre-17th C, you are likely to find someone interested in, and practicing it.
So what to do with all these skills? Some enter competitions, vying to be Shire, Principality, or Kingdom Champions. Others merely display their work, exploring their art for curiosity's sake.
Some donate items they've crafted as Largess -- gifts to the sitting Royalty, so they might be able to exchange these gifts with neighboring Royals, to be distributed amongst their people. Most importantly, if you are enthusiastic about a topic, that enthusiasm can be infectious and others may want to learn. We prize those willing to share their knowledge and teach very highly, either through demonstrations to the public or as formal classes within the society.
