If you just want to roll a normal joint I don't have to tell you how to do it. But I can give a few tips to make it better.

It's important to start with spreading the Tabacco good, a bit less at the site of the roach than at the other side (it will make the joint burn better)
Make sure you get some nice paper for the roach, fold it a few times and wrap the rest around it (don't make it to short) Make the marijuana really small and put it in one line on the tabacco. If you put down the Marijuana good, The tabacco will fall around your marijuana when you start rolling.

For the rest, just try to close it. Your first one will probably be a mess but if you try a few times you will be able to roll a nice joint. The secret is the tabacco. If you devide it good enough you will have no problem rolling the Joint.

Making A Tulip

A tulip is nothing more than a pointybag that is filled with tabacco and Marijuana, connected to a little pipe.

Take a Piece of paper with the length of a Smoking paper and make a pipe out of it. Roll a piece of Smoking paper around it so it stays as a pipe. Stick two smoking Papers together, fold it and stick it together so it gets a bag. Fill it with your own mixture and close it.
Rip off the sticky part of a smoking paper, open the bag, put the pipe in it and connect everithing with the little piece of paper you ripped off. Ready

Super Tulip

A super tulip will blow your head off. Its the same as making a joint and a tulip Together. Just make a Tulip and us a joint instead of a Pipe. This one is heavy to smoke and I advise you not to smoke it alone. :)
