Good luck with the business venture.
My comment is about sharing a building with your husband's wood shop. Wood shops are notoriously dusty. My husband has state-of-the-art dust collection systems in his wood shop and there is still dust with some processes. If your husband's wood shop has a good dust collection system and there is no access between the two shop areas, you should be fine, but I would check that out. You want to be sure it is clean in your quilting area.
