Do like Jensie Jean of Take Two They're Small and use washi tape in different colors and patterns to beautifully mark multi-day events and projects in your planner. A nice alternative to using highlighters, doing this lets you see at a glance what you have coming up and when you'll be busiest. Great idea, wouldn't you agree?
BTW, Russell + Hazel binders, like the ones you see above, are currently on sale on One Kings Lane through Saturday! They're beautiful and can be customized with their SmartDate system.
