I kind of had to laugh at your description because you sound alot like me! Upstairs we have 2 bedrooms and the 'open' room at the top of the stairs that I claim as my sewing room. It has 2 machines in Horn cabinets, a sofa, an antique cabinet with a TV and a pie safe directly at the top of the stairs. When DD is off at college, I move my ironing board into her room and lay projects out on her bed. The running joke is that she has to give me 24 hour warning before coming home to visit. Now that other DD is married, I am also creeping into her room. My cutting mat is on a desk that is in there, I have stored all my fabric tubs in there and I also have projects laid out on her bed.
