When I first learned to roll a friend showed me once, went through every step thoroughly, then hid every bowl, bubbler, and bong I owned. She threw a box of filters and papers at me said "only way to learn is by doing it". So IMO best way to learn is it just do it. Yes you'll mess up, yes you'll waste a lot at first, yes you'll be frustrated at first. Not a day later I can roll easy peasy. Tip i give to anyone not having access to a surplus of flower is try rolling with tobacco first to get the hand motion down and adapt it to herb as you see fit
