I have my extra machine in a rolling suitcase (small), with a small cutting board, a ruler, and a ziploc bag with scissors,thread,pins,extra bobbin,rotary cutter, and a stitch ripper. I also carry a small spiral notebook and a mechanical pencil for notes and marking on the fabric, if I need to. When I'm not rolling it, I make sure it is sitting on the floor so that the machine is upright so nothing leaks out or gets out of whack. It's worked well for me so far (about 3 years), but mine is not an expensive machine.
