Ed,
I did the lines by hand. At first I tried artist crayons, but the texture left bare spots, and I didn’t like the look. So then I went over it with normal acrylic paint using a small brush, then the paint marker for the white.
I did lay a ruler down to keep the lines straight, but no tape.
I just picked up a paint marker in the yellow for the middle lines, so the long sections should be easier.
