Way back in my final year of High School, my major project for Media was a short film, and one of the deliverables1 for that class was a set of storyboards.
For that project, I was either unable to find a storyboard template that I liked, or perhaps prohibited from using a pre-made template, so I quickly threw something together and I’ve been using it ever since.
Feel free to use it for your own projects. I’m licensing it CC-BY, so if you share it around, please link back to https://orismology.me/storyboard.
