'Stranger Things' star Joseph Quinn helped pick out tattoo designs for his character, according to the show's makeup artist

• Insider recently spoke with "Stranger Things" lead makeup artist Amy L. Forsythe.
• The Emmy-nominated artist revealed that Joseph Quinn picked some of his character's tattoos.

The tattoos worn by Eddie Munson in season four of "Stranger Things" are now considered iconic by fans — and they can thank actor Joseph Quinn for some of them.

Insider recently spoke with Amy L. Forsythe, the lead makeup artist who's worked on all four seasons of the Netflix show and is now nominated for multiple Emmys.

She discussed the inspirations behind Munson's ink, fans who are now getting his tattoos on themselves, and how the specific designs were chosen for the character.

"I had my tattoo artist make a flash sheet of tattoos that people in the trailer park or Eddie might have," Forsythe said, adding that Munson would get his tattoos from a kitchen scratcher, or an inexperienced artist, at home in his trailer.

"And then I was having discussions with Joe about what else he would want on him — so the head on his chest he chose," Forsythe said.

Since season four aired in late May, fans have pointed out that Munson's tattoos — specifically the puppet master and six bats on his arm — foreshadow his fate.

As Forsythe told Insider, that wasn't intentional.

The bats were a filler tattoo inspired by Steve Harrington's fight with demobats, she said, and the puppet master was a nod to Vecna and how the villain controls his victims.

But regardless of the different inspirations behind each tattoo, the process for applying the temporary ink was the same.

"They're just regular lick-and-sticks that we have to apply every time," Forsythe said of the tattoos. "If Joe's working three days in a row, they'll generally stay put. But anything that's in an abrasive spot — like the puppet master or the bats — you'll have to apply them a little bit more frequently."

One example of that, Forsythe said, occurred when they were filming the scene in which Eddie leads the Hellfire Club in a game of Dungeons and Dragons.

"Whatever they treated the chair he was sitting on with, it kept rubbing off on him," she said. "One of the fans was like, 'I think he has seven bats.' And I was like, 'Well, actually that's dirt. That's from the chair.' But it does look like a bat!"
