At my LQS, you can use their large workroom upstairs (with prior notification) at any time there's no class or event scheduled. There's a ton of room and lots of tables that can be moved for sandwiching quilts, etc. It gets you away from phones and other interruptions so you can totally concentrate on your project if that's what you need, or it's fun to go with a friend and sew for a few hours in neutral territory. You bring your own machine, etc and it's solo work, not a formal group or class with advice available. The rate is $5 per hour per person.
