Really organise your planner with one of my organiser rulers.
Ruler can be used as its normal purpose, however it can also be used as a page marker (using the HEART at the top of the ruler) - meaning you'll know exactly where you are in your diary.
The ruler is printed with centimetres and has 6 holes for you to move it on and off your organiser easily.
20cm in size.
