What draws you to witchcraft? Tradition? Nostalgia? Curiosity? What makes you a witch is how you perceive the craft, there is no rule book with steps and how-to's... despite those who try to tell you there is an sell you one...
If being a witch is all in your head, that is perfectly fine, witchcraft doesn't have to cost you a penny, this is the beauty of traditional witchcraft.
No need to buy expensive candles, mats, or a bag of crystals, if they make you feel spiritual, and you like them, then go for it...
But anyone can buy things from a store... a true witch uses what comes from within, everything else is extra...
