Sometime in 2011 I posted a tweet that said “Too broke to afford a light box so I’m tracing my work on the window”. While that’s something we can laugh at, it’s also a real issue for many young artists. I wasn’t always able to go to my school’s library to use their nice light table. Not everyone has the money to get a light box and not everyone is a student with access to a light box. That's why the world invented tracing paper.
