I usually just keep a private google spreadsheet to keep track of my commission work, but I realize that leaves my commissioners sort of in the dark as to where I am in my current workload, so I figured I'd set up a public trello for people to keep eyes on if they want to know what my progress is or how close I may be to another commission opening (or in this case taking work from my queue)! Do keep in mind though that I tend to work in random order, so the names are in no particular order and I tend to jump around except for specific due dates.
