hi willow..that sounds like a simple yet effective ritual. (simple + effective being the best combination)
so are you solitary by choice or would you prefer others? for me, its so much easier to do spells and rituals alone, without people trying to judge me ya know? but on the other hand, a coven can probably cast some powerful magick, depending on how adept the members...and how potent the pot? hehe

tip: a good place to try and start/join a coven is actually www.meetup.com do a search in your home town for witchcraft or witches or pagans. you get the idea. i tried it and i met about 10 witches in my area. unfortunately they werent very knowledgable. oh well
