I would say that is about right although some quilts are more difficult. What I mean by that is as a longarmer will get quilts that are not squared, tangled with thread and not enough batting or lining. I usually call the customer and discuss this with them and charge them a fee. This does not happen all the time but once in a while it does. But normally 6 hrs is good for a pantograph. Custom quilting and ruler work takes longer depending the size of the quilt.
