You can only tat with wire or over wire for this technique.
Tatting with wire
The only differents here is when you look at tatting overall, normally you will use thread to tat with, but here you will be using wire instead. Tat like normal (A).
Tatting over wire
When inspired to make a crown or mask or even something that needs something more than starch for stability, wire is use as a base for the project.
You will only have the core thread that gets replace with wire. You will have to tat over with thread (B).
