I have an 8 x 17 for JUST my longarm (12 foot table) & customer quilts and wish it was a lot bigger. I want to add a cutting table for a bolt of batting or two and I want an ironing table. I just don't have room for that now. If you're adding fabric storage, you would need to add a lot more room. I have a long shelf that is behind me that has all my working tools and 2 5-shelf shelves for storing customer quilts. I also have a stool for those times and a small table for putting the paperwork and pen for calculations, etc. My longarm also has a separate bobbin winder....that had to go on its own little table near the electricity...........so -- long story short -- I wish the room was 12 X 24 or so!!!!
