I dry my trimmings, then freeze them...
Then I crumble them and sift through a silkscreen...
It comes out a little green from leaf material, but it gets me and my buddies high as can be...
Sometimes I press it into hash or just sprinkle the loose kief over my headstash.... super pot...lol...
to press it I just put the kief in a cig cellophane, tape it up, and squeeze with a big pair of VISE GRIPS between to flat steel bars...
squeeze until you can't re-tighten anymore... let it sit for about 2 minutes and it should be a nice little slab now...
hope this helps...
