It is subject to intepretation as well. My definition of freehand means it is 100% yours, not a panto at all! To me following a premarked design, be it a panto, a stencil or a drawing done on tissue paper is not free hand. Yes you are manipulating the machine without aid of a computer with your hands but you are simply tracing over a design not free handing it with no pre marking what so ever. In my mind the definition of freehand means NO MARKING and having NO PATTERN to follow.
E2E or End to End can be free handed or following a panto. An all over stipple or abstract design can be considered E2E as well as a pantograph with the same motif repeated from one end of the quilt to the other.
