Inktober is a drawing challenge that occurs every October. The goal is to inspire people to do one ink drawing every day in October. There is a list of prompts online, and you can use them or not. You can post your drawings online with hashtags to make sure that they are seen by those groups that you want to see them. In October, 2018. I followed the prompts and did one drawing a day. When you hover over the images, you will see the prompts.
