The hard work is done. Now it's time to start using your wreath in your celebration of Advent. The first thing to do is to bless the wreath. Traditionally, this is done on the First Sunday of Advent or the evening before. If Advent has already begun, however, you can bless the wreath as soon as you've finished making it. You can find instructions for blessing the wreath in
How to Bless an Advent Wreath.
Anyone can bless the wreath, though it's traditional for the father of the family to do so. If you can, you might invite your parish priest over for dinner and ask him to bless the wreath. If he can't do it on the First Sunday in Advent (or the evening before), you could have him bless it sometime in advance.
