I can't read or sleep or ride in the backseat without getting car sick. However, I have no problem working on my EPP in the car. I think it is because I look up when I'm pulling the thread, I think that little bit of seeing things prevents the motion sickness. Most people think all I do is handwork because that is all they ever see me working on, but in fact I've only made 2 EPP quilts, just started my third, in 7 years. Have made many more by machine in that time.
