Speaking From Experience - Calendar Research

I then started to look into different designs for the calendar... I wanted to design one which would work just sitting on the student's desk. Easily visible and easily useable!

This one could be quite hard to design... plastic base, but looks pleasing.
This is an idea I was thinking about... just a ring binder... so you can literally just pull off the tags on seperate pages.

This is a more complicated design. It would work but I do not know how to go about finding/making the plastic.This is my favourite design, a simple flip calendar with a bind at the top.... I think I am veering towards this idea.

Much the same with this one...
