Best way is you crumble into your palm, add a pinch of tobacco, lay a paper over the top and then flip your hands over, roll with thumbs facing out (leaving two fingers on each hand to tuck).
This is the very best enhancement of all time for rolling joints. A very simple device, and quick to use after some practice. I've used one for many years, so I can attest they roll immaculate reefers of perfect circumference along the entire length of the dube for exceptional even burning.
Another excellent enhancement is the BXB Electric Mini Grinder, which is just a few inches in size and can be used to finely chop hash and weed for the perfect joint.
