I belong to both a quilt club and several guilds. For our quilt club (not technically a non-profit, since we are a club in a adult community), we have a charity group that meets once a week. As far as the guilds go, they have smaller groups that either donate fabric, material, and/or time (i.e making blocks or pillowcases) to a nonprofit (one example, QOV) or make their own quilts and items that they donate to a group of their choice (like a homeless, domestic violence, or teen group).
