I decided to make the calendar myself because of the hilariously overpriced calendar-making-service in the printshop.
Materials that I will be using are duplex, cotton fabric (navy blue perhaps) to over the duplex cardboard and metal card rings to bind them.
-Making the board
Materials & tools used for making the calendar:
-Cutter & Ruler
