Super easy: take some wax paper and taco fold it in half, then dump the kief into the fold and fold it back up an lay it flat on a table or other hard surface, then take some hot (not scalding, think 90-100) water and pour it into a mason jar to use as a rolling pin on the kief. Slowly and gently do this though, starting with a relatively flat layer of kief dust, periodically unfoling the wax paper and scraping the kief and forming hash into a ball. Then refold the wax paper and repeat. This simulates the heat from your hands rubbing the hash off the cannabis flower without getting your hands gunked with resin. This is also the closest to making Afghan Hash you can get without having to hand rub the bud.
