I love Terry Pratchett's witches. In Wyrd Sisters, there is a scene where Granny Weatherwax, Nanny Ogg & Magrat conjure up a demon. Magrat, the newbie, loves paraphernalia:
"I always say you can't go wrong with a good Invocation," said Nanny. "Haven't done one for years."
Granny Weatherwax frowned. Magrat said, "Oh, but you can't. Not here. You need a cauldron, and a magic sword. And an octogram. And spices, and all sorts of stuff."
Granny and Nanny exchanged glances.
"It's not her fault," said Granny. "Its all them grimmers she was bought." She turned to Magrat.
"You don't need none of that," she said. "You need headology." She looked around the ancient washroom.
"You just use whatever you've got," she said.
She picked up the bleached copper stick, and weighed it thoughtfully in her hand.
"We conjure and abjure thee by means of this--" Granny hardly paused-- "sharp and terrible copper stick."
The waters in the boiler rippled gently.
"See how we scatter--" Magrat sighed--"rather old washing soda and some extremely hard soap flakes in thy honor. Really, Nanny, I don't think--"
"Silence! Now you, Gytha."
"And I invoke and bind thee with the balding scrubbing brush of Art and the washboard of Protection," said Nanny, waving it. The wringer attachment fell off.
"Honesty is all very well," whispered Magrat, wretchedly, "but somehow it isn't the same."
"You listen to me, my girl," said Granny. "Demons don't care about the outer shape of things. It's what you think that matters. Get on with it."
Alright, now, I don't believe in demons, but I like the point that this makes about magickal equipment. Use what you've got! Or make something to use. It's what you think that matters.
