Welcome to my very first tutorial (this is my first one, right?)! I would put instructions but everything you need to know is in the project.
100% by me (I mean I used a backdrop from the Scratch Library, and I have the Snipping Tool to thank for some things, but I mean that I figured out how to do this on my own, like I didn't get this from another project). That last sentence was long. If you are reading all the way until here, you are a human of great patience. I don't know if a lot of people even read the instructions or the notes and credits, but I usually do.
