Fabricist
A fabricist is a fabric freak who knows more about threads than your mom knows about your messes.
"I’m a fabricist, not a magician! I don’t turn fabric into gold, I just make it look fancy."
"This fabricist can tell you the history of every fabric in this store, and you can’t even tell the difference between cotton and a sock."
"She’s a fabricist, which basically means she can make a dress out of a napkin and a sock."
