professional rollers, come here.

I find the easiest way to roll a two paper joint is to put one paper in front of you on a stable surface as if you were going to roll a regular joint, take the second paper and turn it perpendicular to the other, lick the glue and stick the glue of the perpendicular paper to the left end of the first paper. Then you can do the same a second time to extend the length further, this allows the papers to be secure and still allow extra length. I've tried to lick papers together, both lengthwise and they always come apart. So once you have the two or more perpendicular papers stuck to the original paper, fold the whole setup down the middle following the fold of the first paper. This allows the bud to collect nicely in the fold allowing an easier and cleaner roll. Then trim the excess off the top of the perpendicular paper(s). Now you have a double or triple length paper, stuck together nicely with the glue of the perpendicular paper. Use the first paper to guide your rolling, then continue down the other papers and seal off the end where you would put the filter and allow the glue along the first paper to stick. Get the other papers nice and wet and then finish off your Jay. It may be harder to allow the unglued papers to stick, that's why I always twist the end of my joints and then allow for a few minutes of drying to ensure closure.
