Janome makes both clear and metal darning feet. I am going to be getting a clear open toe one. if you look on ebay you will find a great deal on them. just double check that they will fit your model. I would call the people in charge of the classes and get an explanation as to what type of tray or table they are wanting you to have and an explanation as to why you need it. no since in spending money on something that isn't a huge deal and you can make your own extension table for your machine. there is a tut on here to do it. good luck
