FootBook is a reference for more than 100 different feet and accessories for top-loading Janome sewing machines, with photos and text describing each one and explaining how to use it. Each foot or accessory also has a high resolution video demonstrating its use. If you have a Janome machine with a top-load, drop-in bobbin, FootBook is the reference for you. If your machine requires the bobbins to go in a case behind a door in the front of the machine, then FootBook is NOT for you. If you have a machine made by Janome, but branded as Kenmore, New Home, or Elna, and it has a top-loading bobbin, then the featured feet should work for you, especially if your machine is computerized.
