Well....here is the problem....if you do embroidering needle, you better have a LOT of spell components know a rogue about lvl 20+. I would recommend the armor myself just because everything can be stored bought. I got enough of hunting for tradeskill materials with tailoring... GRRR....
However, if you know (or have) a rogue that is into poison making, you can always go merchant farming (not the bazaar) and look for spell components there to make the celestial essense for the needles. Unfortunately, you will only get up to 122 with needles and you will have to do the Ornate Chain anyways. I guess it depends on what you are in the mood for....
I think that the needles would be more expensive, just because of a) components or b) anyone who has celestial essence will charge an arm and a leg. Ornate chain- I wouldn't even try to sell unless back to merchant.... it will take up a lot of room in your inventory and you will have to stop pretty often to go sell your wares.
That is my opinion...I hope this helps!! Be safe and happy hunting.
