Most of the skills can be learned on your own with enough dedication and time. We host a diversity of informational and instructional videos on this website on our video page.
Really, though, nothing can replace the experience of practicing or playing with other people. Find others near you, or encourage your friends to try it! Come to a Flow Festival to find your long lost brothers and sisters of Flow.
There are also a number of sources online to find other videos, or even purchase instructional DVDs. Try searching by the specific prop you want to learn about.
There is a wonderful description of Flow Arts at FundTheFlowArts.org.
