i got a cheap one from a gas station and it worked once, but ever since its just not rolling papers. The biggest problem I have with rollers AND my hand rollin is being able to get one edge under the other and get it rolling, but papers are slipping past each other! Also, when I roll joints I use my fingers to take weed apart. Just how fine should weed particles be for joints? I noticed that if its powder-fine then my joints burn SO fast. I try to make pieces like small bread crumbs then it burns slower. Should I use some other technique or get a grinder? I am not sure I need one if I can use hands.
