I hope you don't mind me giving a plug for my own Facebook page - Pagan Portals Candle Magic. If that link doesn't work, you can copy and past this into your browser: https://www.facebook.com/paganportalscandlemagic
My Facebook page has the same name as my book, which is due to come out in the New Year. The page will have lots of news and information about candles, candle making and candle magic. I hope you will enjoy following it.
Another Facebook page that I'd like to recommend is called The Traditional Witchcraft series and is run by Melusine Draco, based on her series of books of the same name. The page covers all aspects of traditional British Old Craft as worked by the Coven of the Scales. You can find her page here: https://www.facebook.com/TradBritOldCraft
Melusine's books and my own are published by Moon Books.
