Hey folks, building a kit and have a very basic question... When sheeting, how do you figure out where to trim the sheeting so that it is half way on a stringer The plans suggest using bright colored chalk to mark the stringer and then wet the sheeting and press it against the chalk to mark the back of the sheeting. And then cut in the middle of that. Tried it but the chalk didn't really mark the sheeting all that well. Used my kids sidewalk chalk. Any other tricks to make this easy?

Told you it was a basic question.

Thanks!!

Dave
