Somehow raising dues from $3/year to $15/month seems like a "guild killer". But that aside, we use members to give programs about 1/2 of the months of the year (as a large guild we do have the $$ to bring in some regional teachers), we also have some type of workshop, usually led by members, every month. Sometimes it's just a sew day for folks to work on their own projects, sometimes a class, sometimes a sew day on one of our charity projects.
our LQS also sponsored a bus trip which was a blast-I think guilds and LQS could join to offer some of those.
