I used to get together with a friend and my mother in law once a week to quilt. My MIL and I were working on a quilt for my daughter, but if I had something else I needed to work on, I'd bring that. Our friend would work on whatever she had going.
We had a little tea and some snacks, and visited more than we sewed, some days, but I think it helped SO MUCH to have the extra input on things sometimes, and I would get something done on a day that I might not have felt like quilting on, otherwise.
