hi ed, i have been making hash for the last couple weeks but want to know for sure if im doing it right. what iam doing is freezing my bud first then grinding it in a coffee grinder and after words brushing out the resin powder to create the solid. Then i place it between waxed paper and press with a hot knife, eventually giving me a solid. is this the proper way of making kief hash? do you have any pointers?
