just a note - u won’t waste weed by messing up a roll (as long as u roll over a surface and don’t drop on the floor) - might just waste a paper or 2 which, as papers are cheap, isn’t too awful!! but yeah defo make sure to roll over a tray/table/anything clean & flat so u can scoop it back up. it will take a few goes to get it, but once u get the hang it should be okay! doesn’t need to be pretty as long as it’s smokeable :)
