I love the room repurposed from the garage! Nice job. No matter how big you make your new spaces, they will eventually be too small. Make the new rooms so they can be repurposed when you eventually sell the house. I sew in a room that has a rolling door and I can look into the rest of the house and am not excluded from what is happening there but my cutting/stash room is to the side of that room so that nobody can look in there without intentionally going to the door. I can leave a mess as long as I want!--(usually longer).
