Hello everyone im actually making some progress doing behsest leves grinding quests/sidequests and ive made some money along the way.Id like to ask some things about crafting

I know already that a way to level up crafting is to do crafting leves but the thing is i can only take 4 leves atm, so what do i do after im out of leves how am i going to raise my crafting job?

for example do I need to buy mats from wards? or grind to gather the materials needed for crafting..?, i currently have 130k gil atm so it isnt much to buy anything. I want to raise my weaver carpenter and goldsmith jobs enough so i can make good quality gear to make money and to gear up my char

sry for the many Questions but crafting is my only concern at the game right now ive solved every other of my problems ive faced so far.. so any help with any info or advice would be appreciated

thanks in advance.
