Very cool looking, but I think I would have difficulty pressing on the bed with my left hand to control the machine while trying to feed the fabric at the same time. Do you put one hand under the fabric to press on the bed and then guide the fabric with the right hand? Or do you press on top of the fabric and push the fabric at the same time? I wish they had shown someone sewing on it in the video. Is a foot pedal or knee pedal really difficult to use?
