I learned to roll perfect joints 25 years ago and used an ounce of weed and a couple of packs of EZ-Wider double wides. By the time I was done with the ounce, I could roll a perfect joint using less than half a rolling paper.
My joints do not run and burn perfect from end to end. I need no rolling school, lessons or videos, no-on does. All they need is a big bag of weed, a couple packs of papers and a desire to roll perfect joints. Some dexterity is helpful too.
