I bought the STID foot for the Janome 7700. I haven't had the need to use it YET. The day I bought the machine the salesman showed it to me and I said not right now. Well...a few weeks later when I went to my instruction class I decided I would buy it. The project that I am working on now is Sun Bonnet Sue...the month of June wallhanging. I will be doing machine applique for the first time...except the test piece I did in the instruction class. The wallhanging has a narrow and then a wide border so when I get to quilting those I will be using the STID foot. I'm anxious to try it now that I hear how great it works.
