Paper Banner - my classroom makeover

I have a whiteboard in my classroom. There is a strip of cork that runs along the top of it. In the past I have tried putting border around it. There is no real reason to do so other than to give it a finished look.
I like things to look finished.
After some trial and error with double-sided tape, sticky-tac, and hot glue, I finally settled on magnets. It worked.
Sort of.
The borders shifted around and when students would clean the board for me, the border would get wet. I waved the proverbial white flag and gave up.
But, I was making a banner for the twins' room and realized that might be an option for the whiteboard.
And ooh-la-la I love the result.
I never wrote on the top 1/4 of the board.
And I never used the cork strip. Whenever I hang anything on the board I use magnets.
So I covered the strip with coordinating paper. Then armed with some twine, a hole punch, and a cutting board, I created a banner to hang at the top.
I cut rectangles from scraps of paper in a size that worked for my space.
Next I found the center at the bottom of the paper and cut a diagonal line from that point to the upper corner.
Using the hole punch, I made 4 holes (2 close together).
I threaded the twine through each and hung it on the corkboard.
Total time: About 30 minutes.
