Here is the first habit tracker I made for my Bullet Journal. As you can see, I had to start half way through the month because I didn't start my bujo on the first day of the month - I just jumped right in! I think the sticker here is a disney tsumtsum sticker and i had it placed sticking slightly out over the edge of the page so that another sticker could be placed back to back with it on the following page. This created a kind of page marker effect, enabling me to get back to my habit tracker at ease.
