It costs $30 per year to join my guild and membership starts in June. If you joine in the middle of the year, dues are pro-rated. Also, no charge if you're just visiting.
My guild has a board that makes all the decisions--my only complaint is that the board tends to be clique-ish. That bugs me. I've adjusted my expectations and continue for the things I like about it: the speakers, the BOM, the charity quilting, and the challenge quilt we're doing this year. I've only been a member for about six months.
