Some ideas for using What Pumpkin products for magic
The most obvious would be obtaining the Homestuck tarot cards and using them, but here are some other ideas:
God tier hoodies/shirts, character hoodies/shirts, Prospit and Derse hoodies/shirts, cosplay pieces: Ceremonial garb
Signless or Sburb Portal necklaces: Cerimonial jewelry
Scalemates and consort plushies: Sacrifices and alter decorations
Backpacks/lunchboxes: Storage for portable alters and other magical items
Homestuck Books: Holy books
Posters and Art: Decorations for alter rooms and holy spaces
Vinyl Figures: Perfect shrine or alter decorations
Keychains: Easy, portable ways to carry a magic charm around!
Music: Background sound for rituals and spells, or meditation. The lyrics for some of them may be useful for spells as well.
