I used to suck at rolling too, bunts and j's. J's took some practice. I had a friend show me how to roll blunts, After that Man being a blunt pro was easy. Also depends on the weed alot, If you got some really dence buds you gotta break em up nice and loose,
I like to break up the bud really fine then roll it back up just tight enouf for a long lasting burn.
