ok heres my take, you use what ever set up suits you, a pantogram is a picture, and just think if you have a regular sewing machine, doing it, you will not have much room in the middle of your machine, cuz you have to roll it up in the middle, so think about that, i DO long arm for others, and love pantos, but sometimes if one doesnt draw, its kind of hard, i dont draw, i like pantos printed on paper from www.goldenthreads.com they have nice ones.
good luck
