For those interesting in stringing their own heads this is a prtty goood instuctional website:

Medicine Man Lacrosse Blog has a post http://www.medicinemanlacrosse.com/blog/how-to-string-a-lacrosse-stick/ Its a helpful resource for those looking to understand how to string their own lacrosse stick. It can help many players understand the concept better and thus help them to develop as a player. It also will save them money.

Alternatively, many of our CHS players have mastered the art so contact the CHS coaching staff and ask if they know.  a nominal stringing charge would be appropriate (~$10).
