none of the above, making hash out of it, would basicly just be wasting time... it doesn't make it anymore strong, or anything... and Masta, how the hell you figure you're going to get 1.5 grams of hash, from .5 gram of keif? lol....

smoke that shit in a bowl...

on a side note, if you wanna do something really intresting (i saw this in a thread a few days ago and IREALLY WANT TO FUCKING TRY IT) make some honey oil, and make this 'dough' out of the keif and honey oil... oh man that sounds just fucking great...
