I would have a room big enough for a large table to cut out my fabric on, sewing table with lots of side drawers, lots of windows for natural light, little ironing board table to the left of me to use while I am sitting down. Lots of shelves up and down the walls. Laminate flooring. Couple of easy chairs to relax in. Special containers to go in some shelves for projects being worked on, and fabric being stored. Just the right shelving for all my sewing books/magazines. Plenty of out lets, Plenty of hooks on certain areas of the walls to have cheerful items. Nice music playing in the background. Just the right window treatment. I am working on this now, but a long way from it. I have the room which is a bedroom right now, but in the process of turning it into full sewing room. Bit by slow bit.
