I do weekly for years now but like you mention time spend quilting goes down. I also ended up being the "teacher" even though I did not want it. Often times they just need friend time and we sit and talk. It is OK. It is only one evening a week and I can sew all the other ones on my own. We always meet at my house as I have the woman cave which is what you seem to have too. I did end up being the one that provides food and wine most of the time but some bring goodies now too. This is also the small group I go to quilt shows with and do other quilt activities like visiting quilt shops. Maybe set a time frame and try it?
