At the Divine Liturgy, during the Liturgy of Preparation, when the Aër is to be placed over the Gifts (the Bread and Wine for the Eucharist), it is first wrapped around the censer and then laid over the Chalice and Diskos, so that the front edge of the Aër just touches the surface of the table. When not covering the Gifts, the Aër is folded (usually folded 3 x 3, so that when it is laid out flat the creases will form a cross). The Aër normally has a cross embroidered in its exact center, so that when it is folded the cross is visible.
