Halloween—or Samhain, as it is known in many ancient traditions—is the thinning of the veil. It is the one night of the year when the spirit world brushes against the physical realm. For crafters, gamers, and magickal practitioners alike, blending the aesthetic of a "lovely craft" with the mechanical ingenuity of a piston trap creates a uniquely powerful, exclusive ritual.
Light the four candles at the cardinal directions. Do not use a standard circle. Instead, draw the Exclusive Sigil (heart-piston) in flour on the floor. Place your lovely craft piston trap in the center.
