The feast of January 6th in Ireland is called Nollaig na mBean or Women's Christmas
At a traditional Irish Catholic mass, frankincense, gold, and myrrh are blessed on January 6th.
You can take some Epiphany water, water that's been blessed on the 6th, home and sprinkle some in each room of you house
It is also customary to give gifts on the 6th as well. Not as extravagant as Christmas, but something that they might like
It was also a tradition in Ireland to burn a strip of holly used as a Christmas decoration.
Another Epiphany tradition is to light a tall candle and put it in a window. This is meant to help the three maji find their way along the night.
