I really wanted a calendar large enough to see the month-at-a-glance without flipping pages in my planner. I decided to make my own.
What you need:
22×28 poster board
I started measuring out my line placement. I measured a 1 inch space on the right side of the poster board. And measured a 1 inch space across the bottom of the poster board. I measured from the bottom going to the top, every 3.25 inches on the right side making room for 6 rows. I measured 3.5 inches from right to left across the top, until I had 7 rows. The larger space on the left side I will use for monthly cleaning reminders.
I added sticky notes where the dates for September 2012 will be.
