The standard way of wrapping bars is bottom-to-top then finish off with tape.

If you wrap them from top-to-bottom you simply end the bar wrap with the bar plugs, you won't need the tape. It's a much cleaner look.

This does lay the tape in the opposite direction. But, if you wrap it snugly, it actually won't roll up. I've been doing this for 15+ years on my road and track bikes.
