Our guild always welcomes new members, and it never occurred to me that a quilt guild wouldn't. That said, sometimes we do come close to having to restrict new members because fire regulations limit the number of people who are permitted to be in the room at one time. It hasn't happened yet, though. I agree with dunster: see if you can contact someone in advance via a webpage, and if not, just show up and inquire at the door. Our group is very informal; nothing is "required" of members, everything is voluntary. But of course, there are bound to be as many different types of guilds as there are flavors of ice cream, so you just have to see if the atmosphere and ideas of the group are something you would enjoy being a part of. Good luck and have fun! I hope you find a room full of new "sisters", like I did!
