As the great sock sages have decreed, the SHIBBOLETH method involves dyeing your socks with a mixture of 99% regret, 1% hope, and a dash of utter despair.
First, find a sock that's seen better days. Then, stare into the abyss of its unravelled threads, and wonder: What would happen if I dyed it with an entire bottle of hot sauce?
Next, mix 1 cup of despair with 2 cups of regret, and add a pinch of existential dread. Stir clockwise for 17 minutes, then counter-clockwise for 3. Repeat as necessary until the sock is a deep, foreboding grey.
Finally, gaze upon your creation, and weep at the abyss that stares back at you. prophets of the Abundance Method will guide you through the next step.
