How do you use hand signal as an usher of the church?

Ushers have a number of hand and body positions to communicate the need for fans, programs, available seats, prayer, scripture reading, etc. The number of hand and body positions may differ by denomination and from church to church. In the Baptist church a common body position for ushers during prayer, used to block entry into the sanctuary are arms crossed across the chest. Also, ushers do not typically close their eyes during prayer as they are to always be alert to the needs of the congregation. Hope that helps.
