THE FRUGAL WITCH

Instead of buying garb, go to a consignment store or the local Salvation Army shop and find something funky that can be used as witchy garb. For instance, if it is black and lacy, any shirt or skirt is likely to look Pagan. Or keep your eye out for old Halloween witch costumes at yard sales.
Instead of buying an expensive metal chalice, go to the dollar store and buy a glass goblet. Decorate it with glass markers or ribbons if you want to dress it up a little.
Instead of using fancy candle holders, get some inexpensive glass or pottery plates (bowls work, too) and sit your pillar candles or votives on them. Just make sure the containers are fire-safe and that the candles won’t tip over. Instead of a pricy athame or wand, go out into the woods and find just the right piece of wood and sand or decorate it as needed. If you have one, you can use a wood-burning kit to inscribe mystical symbols on your stick. Or use colored markers, ribbons, feathers, or crystals to make it a little more magickal. But since both tools are primarily used for pointing and directing energy, a plain piece of wood is fine. For that matter, your finger will work, too.
Instead of buying a pre-made Book of Shadows, take an inexpensive binder or folder and decorate it with magickal symbols, a pretty cloth cover, or pressed leaves. Or just find a cheap journal that already has a cover you like.
Instead of spending a lot of money on special spell candles, take a votive or taper (less than a dollar, most places) and anoint and consecrate it for whatever magickal work you are doing. You can etch appropriate rune signs into the candle with the point of a toothpick, if you want.
AND REMEMBER THE DOLLAR STORE IS YOUR BEST FRIEND
