Candle Magic & Magickal Alphabets
Candles increase your chances for a successful spell greatly. In fact, Candles are so effective in magickal workings that one could work magick with only candles as their tools. This type of magic is called "Candle Magick" Carving or 'writing' on candles adds to the over all power of your spell, using a magickal alphabet adds mystery and a connection to our ancient 'magicians' of the past.
I frequently use Pictish Swirl Script to 'write' messages, and words into my candles for spells or rituals, it is an old script used by the Pecti-Wita magical tradition. I find it easy to use once on a 'roll' and much more magickal and interesting looking than my normal 'English' alphabet.
When I 'carve' a candle, I use a simple pen, of course it is a special pen, I keep on my altar, but I find it much easier to control than an 'athame'. Just write on your candle like you would on paper, slowly and beware of how you write, for example, if you want to 'attract' energy to you, you would write from 'top' down, to 'Banish' energy away from you, you would write from 'bottom' up!
