What makes this antique restoration perfect is that the chair almost seems originally designed to look like Finn. It wasn't, of course, but redditor reallylovely saw how its forms perfectly fit as a kawaii version of Finn.
She saw the old chair at an antique shop and saw in her mind the image of Finn on the back. She painted it with acrylic, including glow-in-the-dark paint on Finn's socks and hood. For the seat, she used a pre-existing piece of Adventure Time fabric, but also embroidered details on Jake's face herself.
