I am also new here. However, to explain long arm quilting machine. Long arm quilting machines are the big kids, google Noltings of which I have 2 for my business, but Gammill, Innova, Handi Quilter aka HQ-16. The throat size is 16 to 30 inches in length. Mid-size long arm machine are from about 12 to 18 inches. Then the home or domistic machines on a frame, like Grace frames. All the big kids take time, effort, space (tables can and are up to 14 feet) oh and did I say money. Hope this helps, a bit of understanding of Long Arm quilting machines. I have both 301 two-tone and a 401 plus a fw. Love them all. I use the 301 the most in quilting. As its a straight stitch and that's all it does.
