The sugar leaf I usually save up and make this kief with it now and then.I´m the same - I prefer breaking it up with my fingers when I´m actually skinning up. Never trust anyone or thing which is given or sold all ground up - it could be anything in that bag! I wanna see what I´m getting.
I see you don´t bother keeping the leaves, what do you do with them instead? Or do you simply store them in separate jars?
