Funny...we have secured our contractor to start on my sewing room late this summer. We are building a sewing room over our 2 car garage. The floor space is 23 x 25 however since we have a pitched roof, I will lose a little floor space. We are putting dormer windows on both sides of the pitched roof to open it up as much space as possible.
I attended a forum at MQX in Manchester April of this year where expert longarmers talked specifically about setting up a sewing room for longarm machines and what they suggested. Of course, lighting was high on the list, along with outlets and workspace. Once my contractor puts in the windows and change the roof, I will be able to chart my sewing space on graph paper to find out where I want plugs and lighting. I think it will be a fun project.
