I sew charity quilts with a group of friends. We rotate homes each month. If we end up sewing several times together in the month we sew at my home because I have a very large table & island in my kitchen. Each lady brings her own machine. I do have a few extra sewing machines for those whose machine doesn't transport easily.
At the once-a-month meetings, hostess provides a simple meal - soup & bread, or a large salad, for example.
At the "in-between" gatherings, we each bring our own sack lunch.
I used to sew with a group who meet every Monday at a local grange hall for free. We brought our own snacks. Often Churches will make a room available - often free if you attend that church.
Good luck with your endeavor.
