I have a semi detached 350 sq ft sewing room with two windows. It is just off the side of the garage so I do "go outside" just out the door from the garage. I love the private, separate area. I have my own AC/heat so I can adjust temp to my comfort level. I do use this room to run my cut/sew production biz. It is nice to leave things as they are at the end of the day and not have to be constantly picking up and putting up as I did when I had a room in the house.
