Use the profile toolpath on single lines. Profile ON your lines. If you are using a V bit, you can calculate the depth needed for the width desired, draw it up within VCarve, or machine varying depth samples in a piece of scrap until you get the look you wish.
Or you can draw thin rectangles (say 3/32 x 2") and use the VCarve toolpath.
If you want the marks to go all the way across the stick, make the vectors longer than the stick is wide so the cut starts and ends off of the stick.
Good judgement comes from experience.
