I use sharpie and sometimes 1/4 tape, less accurate.

But a cool one when shaping and therefore sanding it off over and over is to push a couple of pencil leads from a mechanical pencil into the foam at each end. You can always find the original center line that way to redraw it.

I was going to mention toothpicks on each end and one in the middle, but the lead idea is cooler, especially if you use the thicker lead like Yard-o-led pencils use. The toothpick can get yanked out by a plane.

My only other comment is I'm going to set up a container for shaping and glassing--I'm adding at least one, maybe two RV air conditioners that are surplus to my needs and lots of light. Shaping and glassing makes such a mess that it's glaring, even in my incredibly messy shop.
