For the cursor, how thick is the material? If it is thick enough, for the cursor lines what you could do is use a knife and straight-edge to score the backside of the material, mark over the score with a Sharpie and rub that marking back out with your fingers. The ink in the scored groove gets left behind leaving a very fine line.
