I work little by little on completing my crafting logs.
I've made all of the non-housing items for all classes and all the carpenter housing items. Next is blacksmith housing items!

When my levequests reach 100, I spend 1 day doing all of them for crafting (for the achievement).

I try to do the Provisioning and Supply quests for Grand Company Seals. I use the seals to buy mats.
Do hunts to exchange for items to exchange for GC Seals to buy more mats. (An ventures to let me retainers get crystals)
I also try to gather my own crystals if I can. I find crystals in area where I haven't gotten the gathering achievements yet and gather them there.
I try to run Roulettes every day for Lore and gil. With the lore I buy mats.


I go to nodes when they pop to get mats.

Then I spend an hour or two "Crafting up a Storm" and then sell everything on the MB.

It's too much to do in 1 day, but I try my best to at least do Grand Company supply / provisioning and Roulettes every day. If there is time, I gather and and actually craft with everything I've saved up.

What I can't understand is how people can afford to buy tons of V materia and new armor when having no crafting jobs leveled up...
