I have used my kitchen table in the past and liked it a lot. I had my sewing machine about in the middle, had a small cutting mat to my left and a good sized pressing surface to my right. Worked well for me.
I'm in the process of outfitting a new sewing room and am looking at an L-shaped desk unit. My plan is to create a U-shaped work area so I would be surrounded: sewing, quick cutting and quick pressing.
I would still have my full sized cutting table and full sized pressing/ironing board.
