I get a lot of questions about how it’s done, what kind of green screen I use, how many hats and shirts I actually own, and so forth.
I’ll be updating this when I have more time, but for now I can say it’s just one home-made green screen made of paper, and only one red t-shirt and a hat that I modified with paper! The toad hat is the Mario hat backwards, with paper dots taped to it. :)
Then I changed the hues in the computer. The wonder of technology!
