Yeah, what materials did you try?

Dry grass can be a pain - I bundle it, then "roll" it around so that the middle starts to fray (grab both ends and rotate it around kind of like bike pedals)

Leaves are crap.

Try bark? I know birch goes up like crazy. Trick is, flip the bark over, use a knife to scrape the bark into 'dust.' It catches a spark real easy. Youtube has a lot of demos if you look it up. That's the best and easiest tinder I've found. I don't know if other tree bark would work as well.
