My crafting lvl is 69
I have a diagram for an roomy backpack which requires a crafting of 50 to make.
I have the diagram(50), materials and skill lvl but the choice does not come up on a crafting bench or anvil.

I also want to make a set of Aeterna armor. Crafting lvl required 50
With all the diagrams, materials in my inventory some items, like the main chest piece, do not come up at the crafting table or anvil.

I can make Aeterna weapons and med leather backpack with no issues.

Is this crafting broke or am Imissing a set?
thanks for any help offered.

Light armor pieces and backpacks are crafted at the tanning rack. The workbench (crafting bench?) is just for improving armor.

Thank you. I knew I was doing something wrong.
I never thought to check the tanning rack since I have 50 leathers and 100 straps already in my inventory.
