My boyfriend showed me how to use a dollar bill when rolling. You just put the edge of the dollar bill at the edge of the paper after you have put your weed in it. Then start rolling the dollar up. Don't roll it up in the paper. just roll the paper inside the dollar bill. And they turn out perfect and so tight. You can smoke one joint for a LONG time and it seems like it hits a hundred times. Great way to conserve your weed!
