i think it's how the individual percieves their own space. what some call a studio, i'd call their kitchen table, <g>. I wish i had a studio...because in my mind, it would be a sizeable space devoted to sewing/quilting ONLY. my sewing space (and yes, my machine stays out 24/7) is shared with my work office (i telecommute for my job) and a futon and big chair and tv where the kids play video games. I call is my office/sewing room. again, i think it's all in one's own perception!
