If I am unsure whether I am hitting the right angle or the right spot with my line, I put a small dot on the target and focus on it - then it usually works. Is this a good approach at this point? Thank you for the answer(s)! :)

Bit by bit, the practice pays off. If I don't concentrate 100% on CSI and the task, it becomes a painting. Thank goodness your videos are so entertaining, Stan - it helps keep you going.😉
