In the early years of my marriage, I had a sewing machine set in a simple cabinet. Over the years I sewed with that machine in our family room, in the dining room, or in our bedroom in the various houses where we lived. There was always a sewing mess in those rooms.
After my last child left home, we decided to use one of our bedrooms as a computer and sewing room. My husband has a long desk and several file cabinets on one side of the room, and I have a smaller desk on the other side. Not much room was left for sewing.
My husband bought a new, computerized, portable sewing machine for me, and after seeing in a magazine an idea for converting a closet into a sewing space, I decided to have a shelf with a fold out extension built in the closet in that room. My handy husband put up other shelves and lights inside the closet. It works pretty good - not as much room as I would love to have but at least I can fold up the extension and close off the mess.
Now.........if I could just figure out what to do with all the mess important stuff my husband leaves needs to keep around his computer!
