You are an important part in helping parishioners have an experience of God within the Liturgy of the Catholic Church. This means what you do needs to be planned out according to the protocols and policies of the Universal Church and the Diocese.
"The tradition of decorating or not decorating the church for liturgical seasons and feasts heightens the awareness of the festive, solemn, or penitential nature of these seasons. Human minds and hearts are stimulated by the sounds, sights, and fragrances of liturgical seasons, which combine to create powerful, lasting impressions of the rich and abundant graces unique to each of the seasons." (n123. Built of Living Stones.USCCB)
