Marking a Tennis Court

The lines of our tennis court are faint and want re-marking.

My marker is of such a kind that, though I can start anywhere and finish anywhere,

it cannot be lifted off the line when working without making a mess.

I therefore have to go over some of the lines twice.

Where should I start and what route should I take, without lifting the marker,

to mark the court completely and yet go over the minimum distance twice?

I give the correct proportions of a tennis court in feet.

What is the best route?
