I find Jalie patterns very difficult to trace. I especially can't find my line after a notch. This was driving me insane. (That's my professional opinion.) I decided to use a thick tipped highligher pen and highlighted my cutting line. When I lost track of my line I could just find the nearest line marker and move there and then trace back to where I had lost it (kind of like going backwards in children's mazes). In this case I initally decided to make an S size but then after highlighting I decided I'd be better of with the next smaller size. The highlighting helped me recongnize my R line - - it was the line just inside the highlighted one. If you use different sizes of these patterns you could highlight different sizes in different colors as long as the sizes where not too close together.
