A few years ago I started doing Saultoons’s annual “Septembit” challenge. Saultoons provides a theme and color requirements with 30 specific prompts — one for each day of September — and size requirements for each prompt. Typically, most of the prompts require a relatively small image, with the last prompt requiring a larger image.
