What do you do with a plain ol' bulletin board?
Wrap it in washi tape!
This seriously only took me about 5 minutes to whip up. Just stick, rip, and go!
You can see that it's not entirely covered. I just did a quick border with some chevron washi tape. I didn't worry too much about the edges. You don't even notice them unless you get close.
For 5 minutes of time you can't go wrong with this craft!
