personally, i cleanse my house. i wash everything with a cleansing brew, move all my furniture, wash the floors, then use sage smudge throughout the house. after that, i light a bunch of white candles and have a circle honouring the Maiden Goddess.
that's the ritual [edited for personal preference though] that i used when i was starting out. i find it a holiday for cleansing and new beginnings, many choose to worship Brigit, but i've never been particularly close with her.
