How Do You Craft Armour Above Level 7-9?

So I just hit a high enough level to craft 7-9 armour and i'm not sure how to go higher. When I try to increase the level nothing happens. Do I need to go to another city or something? Or when I level it up more will it make higher level brackets appear?

 

Try level up your craftin level a few levels more and then try the arrows

 

There's many different tiers of material. One tier of material can make items for a 10 level range or so. Oak and Copper and such can make items from Lv 1 to Lv 9, but in order to make a piece of Lv 10 or above, you'll need to harvest a new material, and that will go from Lv 10 to Lv 19, then you move on again, and so on.
