It's kinda tricky, isn't it? Well, we know from experience how difficult it is to make a nice joint. Therefore we have a nice guide - with pictures - to show you how it's done. You'll master the art of rolling within no time!
Now lay down the paper in a way so that you'll be able to start the rolling. Place the filter, or tip as we tend to call it, at the beginning of the joint.
Start crumbling your tobacco on the paper. Any tobacco should be fine, but especially when you are not used to smokie a spliff it would be nice to start with a light sort of tobacco. Make sure you don't put in too much, especially in the beginning next to the tip, otherwise you could have a problem with the rolling itself.
Now you start crumbling the weed over the tobacco. Spread it in a constant way so that it's all egally over the whole spliff. The crumbs shouldn't be too big, this makes it difficult to close the paper, but also too small will make it difficult, as the shit will fall out of your paper while rolling.
Okay, here's where the fun starts! Carefully pick up your papers, including all the accesories on it. Roll it a couple of times to make the mix more solid. When it's okay, you should start to try to fold the bottom under the glue stroke. This won't be easy, but when you practice a lot it's the easiest thing in no time. The best way is to try to put it in at the tip's end, then the rest.
