I teach at a university and one of my most organized students tried for years to get me to use Trello! I've tried in the past, but Stephanie's class gave me the kick to try again. I've set up this board for planning and work on my version of Inktober, which I'm calling Damestober. I have inspiration images at hand and in-process and finished works so I can see where I'm at. I'll also be using it to plan my social media content more comprehensively.
The screenshot below is from the iPad app, which is great, because I do my drawing on it and can drop it directly into Trello. Below is my desktop version in a browser, which lets me see more. I'll have to look at what I can put on my phone, now, too!
