I think this is one of the best videos to teach how to do pantographs. I have a Longarm without a computer and have done hand-guided pantographs on a few quilts without any problem. Linda Taylor really explains everything thoroughly from start to finish. I had my sister watch it before she did a panto. It was her first time using a Longarm and she was off and running pretty much without any help from me once we got the quilt loaded! Once you get the hang of it, it’s super easy.
