You just need to make 40 lv 50 insignias, you don’t have to make the entire piece of armor. Embroidered jute ones, I believe.
Just craft 40 of the lowest tiered insignia, or you can craft 20 along with armor to go with them at higher levels to progress your tailoring.
Anything labelled as ‘Master’. Cheapest would be emborided jute insignias.
But if you’re wanting to level tailor anyway it might be worth making some of the higher levelled (and more expensive) ones and do both at the same time.
“Life’s a journey, not a destination.”
They do have to be masterwork though, not all the lowest tier are.
Jewel is easiest.
You make masterwork items at level 50 jeweler.
It costs about 40s total to get there and make the items (for me) since you can just sell back what you make
There is actually a guide on wiki if you look it up.
Also the iron plated dowels for inscriptions count as masterwork items, so you only have to make half as many inscriptions as insignia. Mostly it just matters what you have already collected. Each of the crafting professions except chef has low level masterwork things to craft.
He might start thinking he knows what’s right for you.

There is a drop down filter in the crafting panel. If you check the “Masterwork” checkbox, it will show you all your recipes that are Masterwork, and therefore count for the achievement.
