Since I live in a town home and my studio is the other bedroom and has a lot in it: a HQ16, sewing machine, serger, embroidery machine, and storage there isn't much room left.
I bought a rolling kitchen island with shelves that can be folded for storage. I keep it in the living room unless I have non-quilting friends over. It fits in the studio when I'm not actively engaged in a project in the studio. I've only folded it up once when I had out of state visitors for a prolonged period.
When I want to cut out something really large, like batting, I call one of the LQS's and ask when I can use their tables for this sort of thing. They know me well enough as a customer that this works really well for me. Of course we have a lot of LQS's down here.
