You walk out (first lay) and walk back to the starting flag on the exact same track (double lay). It makes the track easier to follow because of the concentrated (2 layers) of scent.
You don't care so much about the direction of lay initially, i.e the dog won't get confused by the second lay being fresher at the start than at the end, as the initial tracks will be short and you won't be aging them that much. Later on the direction (i.e the dog being able to pick the correct direction) of the single laid track becomes important.
You can also lay into the wind initially for even stronger effect.
