One of my favorite things is my planner bag itself- I am not ashamed to say that I change my bag often but then there are times when I stick with one bag and go for months on end.
I grew up in the smell sticker and Lisa Frank era so stickers have always been a part of my style. I keep a set a productivity stickers, a seasonal sticker book, and then a few other smaller sticker books that I am enjoying at that time in my bag as well. I will be 100% honest- I am a monthly planner so it is very rare that I use the weekly pages.
