At the Great Entrance, when the sacred vessels are brought in procession to the Holy Table (altar), the priest will place the Aër over the deacon's left shoulder before he hands him the Diskos (the priest himself will carry the Chalice). For this reason, the Aër will often have ribbons sewn onto it, so it can be tied securely in place. If there is no deacon serving, the priest will place the Aër around his own shoulders like a cape, which will leave his hands free to take both the Diskos and the Chalice.
