If you don't want to knock out a wall, here's what I'd do. Get the hubby busy cutting out a doorway between the two rooms. That gives you easy access and you don't lose all the wall space you might want for fabric storage. It's also quicker, less expense, less hassle and less mess. And I WOULD put the cutting table in with your fabric. That's my story and I'm sticking to it.
