Wind shards....WHERE?!?

One other alternative is to do Guild Tasks. Perform a level 1 or level 10 task (like making bone rings or brass wire) and you can turn them in for shards. The rewards vary -- some offering shards, some gil -- and the rewards seem to be on sort of a lottery type system -- so you're never guaranteed to get the best possible reward -- but you can get up to 100 shards of a given type.

Botany works well too .

It might, as rumored, be in part due to my high Wind stat, but while I'm running around gathering, I get almost a pure flow of wind shards from Botany. It may vary a bit by City region, but either way, it's a good turnout.
