My new bobbin cam! I'm a long armer! And was constantly having trouble with thread tension! The bobbin cam takes all the guess work out of the mix! There's a small flat screen that mounts on top of the machine so you are able to see the frame of work, and the micro camera( so stinking little it almost hurts)! Is mounted next to the needle on the underside of the machine. I'm having a second camera mounted to the right side of the needle, so I can watch in both directions! For more information look in the blog posts on the quilting board, and contact information. You will never be sorry!!!
