Let me show you how I highlight birthdays in my planner.
I used the CTMH watercolor set to paint in my planner! Yes you can!
I used some washi tape to mark off the area I wanted to paint. The key to this is to not use too much water. Your planner is not made of watercolor paper, but it can handle a little water and paint. Just use some less wet paint brush. (I also used a craft heater to dry it quickly)
A few more awesome features of the planner are the TODAY page marker-its clear and that's a huge bonus and it's the perfect place to keep the sticky notes and flags.
I use flags for things in my planner that can move around. For example below I need to type up the Agenda for a meeting, but if I don't get it done on that day I can add it to the top of my list the next day.
I promise to show you all kinds of ideas this year on how to use it.
