I recently saw a brilliant idea on Do It On a Dime's Youtube channel. I don't know where I've been, but I'd never thought about printing on Post It notes. I tried out it out, and it worked wonderfully. I'm going to show exactly how to print on sticky notes.

If you want the word templates that you can edit yourself, here they are:
I've also created a video tutorial to show exactly how to create your own templates in Word, so you can print whatever you want on any size sticky note:
