Excuse the obvious question, but...

At what level do you start crafting?

I have read in some forums that some are already crafting by level 4, apparently all that is needed to start is to join the Guild and some tools are provided.
I didn't receive any tool to start crafting, I'm playing Arcanist, lvl 6 at the moment.

Do I need to speak to a specific NPC? I'm presently based in Limsa Lominsa.
