I think it all depends on how you feel about being out of the house for periods of time. I have a friend who took a storage unit and finished the inside complete with air-conditioning and she just loves it. Says she can do her thing without interruption. I, also, have a nook in the bedroom. For myself, I do not think it would work for me. DH has health issues and I would not be comfortable leaving him in the house where I could not hear him call. I have had a dedicated sewing room in the past but when we down-sized, it was one of the rooms that had to go. I miss it but you do what you have to do.
