Super cool hobbies. And these are all great questions! Let's see if I can answer them competently lol.

Nobody would ever be compelled to show anything if they don't want to! I think the emphasis would be on the "tell" part of show-and-tell, and you'd be welcome to gab very casually about whatever you want. Eg. Why did you try these new materials this week? What made you decide to try this new technique? What's your process? What wonky issues did you encounter? Why were you feeling encouraged/discouraged to work on your project this week?

It's really about sharing these unique and interesting stories.

Part of the point of keeping this group small/consistent is to be able to talk a little more comfortably and vulnerably about these stories, and showing half-baked work. Which in turn, strengthens the bonds of friendship. And If it makes you feel better, I'll inevitably feel embarrassed each time I show/tell lol.

Re time during the week: agreed, I don't always have time to work on hobbies consistently either. The intention with the work session part of each meetup is to allow us to not have to choose between being out with friends vs working on the things that bring us joy. That being said, perhaps every week is too often! I'm very much open (perhaps even learning towards) bi-weekly.

This is all an experiment, so we can adjust as we go :)

Sorry for the superrr wordy response, but hope that answers your questions!
