For those of you who would like to make your own they are really easy.
You can purchase the mini calendars from edex.com.au (pack of 25 for $5.50)
They are just an easel card that you can search for a how-to video on youtube.
The measurements (in inches) I used were;
1 - Easel panel -11 x 4 3/8 (scored at 5 1/4, 5 3/8 and 8 1/4)
1 - matching card stock panel 4 3/8 x 5 1/4
1 - card stock calendar backing 2 1/4 x 2 13/16
1 - 4 1/16 square piece of card stock for the sticky note box (scored at 1/2 inch on all four sides)
2 designer series paper panels 4 1/8 x 5
You can get one complete calendar stand out of a 12 x 12 piece of card stock.
Don't forget to use a 1" circle punch on one side of your sticky note box BEFORE you snip the corners and glue it together.
Good luck, they are quick and easy to make and are a very nice gift.
