Can you switch?

You most certainly can. I myself am a Wiccan, as well as a Gaelic Polytheist. Outside of circle, many Wiccans have their own individual personal practices that are also important to them, other than the Craft.

I think problems arise when different practices or mixed, or appropriated, that would otherwise negate each other.

Is it possible to practice both Hedge Witchcraft and Faery Witchcraft? I am very attracted to both path, and don’t think I’ll be able to choose one over the other :P
