so which is it? You want keif? or do you want to make butter? It's not like you have so much leaf as it would make sense to do both. The large leaves do not usually have much thc, you realize. To make the keif you can 'dry sift' Go to the paint store or hardware and buy a couple of one gallon paint strainer bags. Put your dry, crumbled herb into a one gallon can with the bag stretched over the opening. Shake, shake, shake the can over a mirror or glass surface and collect the keif with a plastic credit card or equal.
