I was in a hands on class a number of years ago where we learned to double the cardboard, enlarge the middle hole slightly, wrap ribbon around and around (from the middle, over the top, around the bottom and back up through the hole) until it was completely covered. We embellished this backing with beads, ribbons, and such then created a hand tied bouquet that was thread through the center.
I'm wondering what else people will come up with.
