I’ll take a couple of guesses. Downloaded from the internet. Made them in Adobe Illustrator. Payed someone to make them for her. Used A.I to generate them. They come with the camera. She called the company and they mailed it. At least one must be right.
I have always wished Blender had Adobe illustrator type of functionalities, anything that lets you skip a middle software is always most welcomed. Blender Institute should merge with one of them Krita or Gimp guys and mate them software’s, like the Chocobo’s in FF7.
