yeah theres 2 ways i know of to make hash - either by scraping the resin off the leaves (thats how the nepalese hash is made), or get a silk screen, fill with ground up buds/shake, and then after sieving it a while you can get all the crystals offa it - called kif. you then put this in a small plastic tube (like what cheap cigars come in), squash down, wrap it in some paper, wet it and put in the oven on a low heat for 10 mins or so. and viola - hash! fucking potent hash at that aswell.

p.s the bit about the sieving is very sketchy, i only overheard it in a convo so it may not be that accurate. along those lines, tho.
