Sadly, I don't rotate as much as I should. I use different bags on weekends, but my work bag tends to be the same every day for the week. It's truly a crisis right now because I changed jobs to one where I take a lot more work home with me, so my smaller 'work' bags aren't getting rotated in at all (Marc Jacobs Whiskey Satchel, I miss you). I need another large work bag.
