The way you say "glass" makes me think of a Crack pipe or a Meth spizzo. LOL but yea I prefer glass bongs and pipes. BUT the BEST is the VAPORIZER!!! for sure you got to try it!. If your rolling with paper though use the DOLLAR BILL TECHNIQUE for sure!! here it is :
Break your herbs up like usual , bust out a dollar bill(Iprefer the hundred of course). Using one that is a little worn makes the process WAY easier, I roll the bill between my hands to make sure it is the proper consistency for rolling.
OK, So grab the bill and make a little "cup " at one end .(i need pics ...i know)and then drop the herb in there . Ok, now just roll it back and forth a few times just to get it close to a round shape. Then insert the paper between the herb and the dollar. DONT TRY TO HARD DOING THIS !!! JUST QUICKLY STICK IT BETWEEN and then roll it with your finger on the outside of the bill.
Once you get it rolled most way i like to grab the edge and pull it out of the bill. From there it is TWO MOVES. Lick and twist.COMES OUT LIKE A DREAM. TRY IT!!!! you should be able to get the hang of it with 2-3 trys!!!! ask for questions.
