Instructions
I made a stickermule shop for your convenience (and mine, so that I don't have to take orders and keep a physical inventory) but there's a cheaper option that doesn't really take much more effort. Download the sticker files from the link below, then upload them to a custom sticker website to have them printed. I'm currently using Expresta.eu.
If you're printing a round sticker, I still generally suggest uploading the square version of that sticker, then allowing the website to cut the circle out of it. I've also provided the cut out versions in case they help.
