The embroidery machines are fairly compact - they weigh 65 pounds. They can be used in any environment that has a power source. People take them to horse, dog and cat shows and athletic events. I have yet to do that, but I could! They connect to the computer via a hub. The software that runs the embroidery designs can handle up to 72 of these machines running different projects simulaneously. If I had 144 hands, that might make sense.
