Raise the flag briskly to the top of the pole. Pause for just a second, then slowly lower the flag until it is in the center of the pole (literally half staff).

The way you do it is when you attach the flag to the halyard, raise it all the way up and hesitate for a second before you bring it down to half-staff.

The Papal flag should be full staff
