Lots of crafting questions.

Okay I'm buying Artisan gear.
Only need one piece left which is Artisans feet thing.
I know i60 gear is BiS so I shouldn't try to get the i70 gear except for head piece.
For the Artisan Apron should I go +10 craftsmanship and +6 control or should I go and +3 Cp or should I go with +18 craftsmanship and +6 control
Other things I know I need to do is get every class to 50 but Culinary to 37
But for Desyn do I work my way up with weak weapons till I hit 50 and it's 100% good or do I go further.

Since I need 3 Mastercraft Demimateria
Other than that. When I have everything fully melded where do I go from there?
Start on my Supra? then hopefully that i95 crafting item?
Also what should my crafting be up to the mastercraft mine is so far 397 craftsmanship and 385 control

There are really indepth discussions on this in the Disciple of the Hand subsection where you can find the answers you're looking for and more, but while i'm here...

For my artisan apron, I did +18 craft +4 control +3cp. (really it depends on how close you are to each target for craft and control)

The glasses are good. If you can get your ixali gloves at reputation rank 7, they're the same as fully melded artisan mits except they are missing the CP. Sacrificing cp sucks, but they make a good place holder if you're just trying to hit stat targets.

You can make it without culi to 50 for a long time, but once you plan on getting your second master's books, you'll want reclaim (culi lv. 50).

For desynth, you should generally start moving up in item level once you hit around 60-70% chance of success. Anything below that doesn't give you enough of a boost to your desynth skill to make it worth it in my opinion (for leveling*).
