Here's one for those of you living in the Washington, DC area – the National Capital Area Glass Guild (NCAGG).
The NCAGG provides a community for members (including monthly meetings and other special events) and actively promotes the glass art in the DC metropolitan area.
For those of us who don't live in that area, it is still worth a visit to their site &ndash both for ideas for starting your own guild and to browse the member gallery.
