How about having another, invisible turtle that travels with your
line-drawing turtle, perhaps a couple of steps ahead of her?
Something to try.

my name is Shane and i am stumped. My teacher Ms. Andrea and i are
trying to figure out how to make a turtle stop at a line it draws. How
can I make it react to a line that it go back over after it draws it. So
far I've tried using colorunder but it detects the color right away. I
also tried using programming the colors but nothing is working. Please
