dose anyone know how to make custom items if so please tell me??????
This (
http://knightsoftheoldrepublic.filefront.com/info/tutID9) page tells you how to make custom robes. As for other item types you'd just have to extract/use a different type of item as a base.
If you want to make custom models/skins, I can't really help you there, try searching the forums.
