Hi, prudence!
Thank you for the reply. This is exactly the kind of info I'm interested in!

How funny - I'm just wanting to get started with petition papers, as I've never tried it. Do you just write your desired outcome (with focus & intent) and place the paper under the candle while it burns? And for disposal, it seems to me that it might differ with what work you are doing. What is your preferred method(s)?
I've been working with Twilight Alchemy Lab oils and also some of the voodoo blends from their sister company, Black Phoenix Alchemy. I have quite a few different ones, but so far I've used High John, Anthelion, Has No Hannah, and White Light. I have some Van Van, Fiery Wall of Protection, and an uncrossing blend from another seller. (I can't recall his name, but he was recommended on this forum under one of the Hoodoo threads. I've actually been using that one almost daily for about a year, with very good results.)
I love the simplicity and focus of candleburning and I find it very soothing and (so far) pretty effective. I'm not sure what tradition I'm following (LOL), but I'm very interested in hoodoo and have spent some time perusing Lucky Mojo and some of Cat Yronwode's copious info available on the web.
So far I've stuck with votive candles as they are easy, relatively secure and readily available. I'm curious about some of the other candles, like seven knobs or what Lucky Mojo calls the offertory size. What are the benefits of those, do you know? Does it depend upon your type of working?
ETA: Love the idea of handmade candles...did you make them yourself?
