Perhaps a fold down table, similar in style to a Murphy bed, would work well for you. I think you would need about 20 - 30 inches wide and perhaps the same long, have a leg attached to the end to support it while you're cutting. You could even use the space below it when it is 'down' for other storage.
If you made or purchased a nice ironing pad, you could also use the surface for pressing your fabric and quilts.
