It sounds like the only solution for you is to stop making big quilts. If that isn't an option then you'll have to get rid of some stuff or reorganize your room. Maybe think about shelving that goes up the wall to make some more floor space. I think it would be a lot easier for you if you could pull the machine away from the wall and use a folding table behind it. When you're done it can all be put back up against the wall.
