If you live in a big city and love weaving, chances are you will be able to find a weavers' guild in your area. They are also in some smaller cities and towns, though their presence in these areas are less common.
It's worth it to visit a larger city if you want to join a weavers' guild, because you will have access to a lot of information and activities for weavers. You will also meet people who can give you advice and information about your favorite weaving techniques.
I have a friend who is a member of a weavers' guild, and I have gone with her to several weaver's events featured by the guild. If you love weaving, you will find all that you need in activities of the guild. Whether you want to learn about the history of a particular part of weaving or take a weaving class, a weavers' guild is where you should start.
