You need far less than you're sold
The honest starter kit: a candle (something to hold your gaze), paper and a pen (to draw sigils and write intent), salt (old, cheap, and genuinely useful for marking a space), and a quiet minute. That's it. Everything else is comfort and ceremony.
Buy tools as you grow into them
A blade, a cup, a deck — they matter when your practice reaches for them, not before. A tool you bought to feel like a witch does nothing. A tool you reach for mid-working has already earned its keep.
