I was reading about "the 7 faculties of the soul", which first showed up in Druidic thought and later in Catholicism. And that got me thinking about the "7 deadly sins", "the 7 virtues", 7 colors, 7 musical notes, etc. It occurred to me that a large canvas with a great big "SEVEN" might be a great way to remind oneself on a daily basis to use the virtues and faculties and not to partake of the sins!
