I've been plan to do this a long time ago... but no time to do it, and no artworks. Probably somewhere this year (wahh...). Will let you guyz know.
I used to download free calendar from 72 Lounge. They have a very cool designs; a collective artworks from different designer for each months. But too bad, their site is now down.
Anyway, i've found this cool pdf calendar from Love. Obsess. Inspire, designed by Gleaux. Download it and ready to print. This is one of the nicest calendar out there. Let me know if you found something nice too!!! Sharing is good... heheheee
