I just finished teaching a class on free motion stitching, which I call "Doodling"  It was great fun and the ladies are on their way to some lovely quilted wall art.  They just have to finish!  That seems to be the problem with classes that you can't complete in one or two sessions.  You still have to find time at home to do the work.  The only way anyone gets good at anything is "Doing It!"  So keep on keeping on.
