Issue
Spellbound Cloth with durability used cannot be used to make more Fancy Amulets for TC6 due to CraftTweaker 2 script missing wildcards on lines 76 & 77 of thaumcraft.zs

I believe that is intended, but I'll double check.

Yup it's intended :)

So the bug would instead be that the cloth is not consumed then?

Yep I didn't think about that, woops :) will get it fixed.
