Yes, they will be in Paducah. Using a design up to 10 inches is what I have read some people recommend. I haven't tried one that large yet. I'm considering getting the Precise Pantograph System so I can do Pantographs. I don't think my hands would be steady enough to use a regular pantograph system.
They usually have several machines set up and the shows and you can try them. The are great at answering your questions and ready to show what it can do. I have seen them at a couple of shows and after seeing it in Paducah last year I made the decision to buy it. I already have a Little Gracie II frame, so all I had to buy was the machine and it works just fine on it. I look forward to visiting with them again in April at Paducah. I will be there Thursday, Friday and Saturday.
