On mine I have a circle lined with salt and an assortment of candles in various positions around it. The candles tend to change depending on what I'm doing. To the right is an incense burner and a small pile of herbs and dried leaves. To the left is a glass, which I usually either fill with water or wine. And of course, all around it, are books. I tend to not change it around the holidays, but it does change according to what I am doing.
