Getting a costume
After your first month a costume or "garb" is required to participate in battlegames. The simplest option is demonstrated by John Rambo in this video as he makes a tabard.
Basic garb is easy to do if you have access to a sewing machine. If you don't, there are machines available at most Arts & Sciences meetings and people that are willing to teach you how to use them.
Tabard: The most simple garb, a rectangle with a hole in it for your head. Usually held down with a belt or sash around your waist.
T-Tunic: Only slightly more complex than a tabard. A loose fitting T-shirt can be used for a pattern.
Belt: A simple strip of leather with a metal ring attached to the end is the type of belt that most wear during battlegames. A bit of paint or carving can make a basic belt look very nice.
Sash: A strip of cloth at least 2" wide that runs from hip to shoulder to indicate which class you are playing during a battlegame. No sewing is necessary, but a bit of work can make them look very nice.
