Not exactly a power tip… so don’t rip me apart because I know this isn’t high tech. Do you get annoyed by cluttered post-it’s crowding your dashboard? (See below)

A lot of times you can’t read them easily and your eyes just miss them. But I’ve found a work-around. First, open up Text Edit or your favorite word processing app. Type your message there and increase font size as large as you like. I used 100pt in this example. 
Now, press down Shift + Command + 4 to take a selected screenshot of your text. The image will save to the desktop. Then drag the image to the Safari icon in the dock. A new tab will open up with your image in it. Now, take a web clip of the image. It’s that simple. Now you have an easy to read post-it.
