As I've mentioned before, I consider myself a Dianic Witch--which often means a witch who appeals to a great goddess who encompasses all goddesses. Other variations are witches who honor only female goddesses (many witches worship male and female gods).
For me, I worship many female goddesses, but also focus most of my attention and power on the goddess for whom Dianic Wicca is named: Diana/Artemis. If you've met me in person, you know that I even have my Goddess of the Hunt tattooed on my left arm as tribute to her.
But how do you honor a god/goddess in your home?
In general, a witch should have an altar--a sacred space for all your witchy items. But you should also have a special place set aside in that altar to show respect for your patron god/goddess.
I've had my bust of Artemis for about a year or two now, but it wasn't quite enough. Then, for Christmas, one of my friends gave me this beautiful, silver antler candle holder. It was perfect for a goddess often pictured hunting stag.
I then adorned it with things I felt would please her--flowers, coins, crystals, and other trinkets. It's important to do this with intention. Consider how they might accept these tokens of your reverence. I kept my charms and the holder silver, as that's a color/metal often associated with her. When I can get my hands on some thistle, I plan to add that as well as it's a plant she is often associated with.
Do some research. Chose your patron god/goddess wisely and consider elements that best represent them. Show them that you care, and they'll return the love.
