Fastest way to level up jobs like carpenter, weaver, etc?

It's best to use triple turn-in leves for leveling crafting jobs.

With the changes, I would consider doing anything except triple turn-in leves, provided you have a stockpile of leve allowances or are willing to wait longer to cap skills. Filling triple turn-in orders is time consuming, whereas the other crafting leves are much faster, and now often only reward slightly less xp.
