Hey y'all!

So for October I have been doing a daily drawing (mostly just simple stuff) and I was thinking of trying to do something different next month and do a 'big' project, something I work on for the whole month of November. But I'm unsure of what or really...how. I do a lot of my art at work (I have a very quiet job that allows for a lot of downtime) and don't often have time to do art in my 'off' time. So if I wanted to do something 'big' it couldn't really be a literal 'big' piece like a painting or drawing unless it was digital.

Has anyone else done a Month long or longer project before? What did you do, how did you manage time for it, what media did you use?
