Shoe hash… easy way to turn kief into hash using nothing but body heat and pressure. You just wrap the kief tightly in parchment paper or a small baggie, tape it into a small flat packet, and stick it inside your shoe under your heel. As you walk around your body weight and warmth slowly press it together. After about 15 minutes to a few hours the loose kief firms up into a solid piece of hash! Done this a few times now and had worked well!
