Anyone seen this iron on ghost patch idea..?

What I have been looking for is an iron on ghost patch that either looks like a 'DOPE' ghost or something that resembles or looks sorta like a Teresa boo ghost patch but the colors look negative. Meaning the body of the ghost or boo looks black or intensively dark purple or a deep dark midnight blue, but the line work that outlines the body & shows the eye shapes of the boo are in white?

I ask because I'd like to get something like that so I can get it to put on one of my custom hats?

Where might I get such an item? Anyone know?
