Well I didn't even bother to read that guide, rolling a "joint" is simple, you place your rolling paper in one hand right or left whichever feels more comfortable In the U.K we use a thing called a roach which is a thin bit of card rolled in a tube at one end to help maintain a clear airflow and give your spliff some shape so you have the roach at one end you don't necessarily need it but I would recommend it then you place your nettles into the paper again in the U.K we mix a small amount of tobacco in to maintain an even burn I cannot recommend this as tobacco is severely detrimental to ones health, so you got your nettles in the "joint" you then roll the paper in your hand caressing it to the shape you want us bosses in the U.K pride ourselves on the cone, anyway once you got the shape you tuck the paper behind the roach and roll up simple as fuck. One time for your muthafuckin mind. The tighter the roll the slower the burn, however too tight and it will just go out all the time.
Edit: So I went back and read your guide pretty good I was put off by the length; I couldn't see why you would need to write so much for something so simple you went into a lot of detail so fair enough.
