I have never been able to roll a blunt "properly", even after smoking many years, and I do not know what your issue is, with rolling them, but I can share how I do it. People have gone into great detail about how to split the blunt, so I'll skip that, except to say, make sure you are not getting stale blunts, because that can also make it more difficult. When you are rolling the blunt, don't try to do it in your hands, or with your fingers. The easiest way is to put your weed close to the edge, and roll it over on a hard surface, like a table or book, and just keep rolling it over like that, applying light pressure, so it is not too loose. Lick to seal, dry it off, and you're straight.
