I forgot about the start/stop feature and the the speed feature..I use these alot-- can slow the machine down and then my grandchildren can use the start/stop button without using the presserfoot.........their poor little legs just aren't long enough ! Or if I am quilting a straight line from one end of the quilt to another I do not have to use the foot peddle.. did not think that would be relaxing- but it is :!:
