Bulletin Board Borders

I love using a double border on my bulletin boards, with white on the inside and another color on the outside. It takes a little more time to put up though, especially since my teacher-OCD forces me to use a ruler to measure the spacing between each border so it's even.
 

After you've measured, you can put up the inside-border. (I really like using white for all my inside-borders.)

Here's a close-up:

Then staple up the outer border, simply following the edge of the bulletin board.

And voila!  You're done!
