We've seen this idea before, but perhaps not done so beautifully. Create your own butterfly specimens with paper (or fabric) and display them in a shadowbox.
It's a simple and lovely way to show off some of your favorite paper - decorative paper or anything interesting in your recycling bin (maps, old books, sheet music, old letters) and could certainly be done with other bugs like beetles.
You can see this project in the September issue of Home Beautiful which you can preview here.
