I have both sizes of the Maga Hoop and wouldn't machine embroidery without it. There is a sofware program available that's helps with sizing so the design fits within the dimensions of the frame. Hooping is so much easier. I hated hooping and almost quit machine embrodierying because of it. I use mine on the babylock machines. They have Maga Hoops for most machines. I had a friend come over and look at mine and she was impressed. She went home and ordered her own. You won't regret purchasing one. The jumbo mega hoop is for the larger quilting squares. There is a DVD that comes with it as well.
