Great info! I'm prez (until Jan) of a 180 member guild that meets monthly in the morning and then repeats in the evening for those that can't make the mornings. In July and Dec. we have evening only potlucks (July is our annual challenge) and hold a show in late Sept. So programs in Sept is prepping for the show. We also try to have our members present the programs in Jan. & Feb due to possible weather cancellations. We are fortunate (in KC area) that there is a quilt network that holds a fair for presenters to connect with guild program chairs. We also try to have a workshop or sew day once a month.
Probably one of our best "programs" is the beginner quilt class that is offered for all members (and can be repeated) as it really draws in new members and keeps us dynamic. It's 5 classes (6 hrs each) that teach the basics and includes mentorship which really helps get new members really feeling part of the guild.
