The only thing that is good for rolling is practice.
Buy an ounce of weed and two packs of EZ-Wider double wides.
By the time you get to your 50th joint, you will be down to cutting the paper in less than half to roll your joints.
If you are still having trouble rolling after 50 or 60 joints, you should hang it up and quit smoking joints because they are a waste of weed anyways.
Smoking bong hits is the most economical and efficient way to smoke marijuana.
