First off use swishers to learn on there easier and if they are not sticking then you need to use more spit. Im a blunt master that what I do roll BLUNTS!!!!!!
If still having a problem try using a little honey or chocolate syrup to seal the deal. Also if your rolling them to tight try not to roll it like a joint just use enough paper to seal it them you can pack some more weed in if its a little loose. Hopes this helps. Peace :rastasmoke:
