Not my greatest floral effort; it was too hot and humid when I made these and I was struggling with the icing texture. But anyway, buttercream with fondant/gum paste butterflies. To make the butterflies, I cut out corners of a cardboard box and laid them in a flower-drying rack. I cut the butterfly shapes with a fondant cutout, folded them slightly, and let them dry in the rack. Then I brushed pearl powder on them and piped on chocolate buttercream bodies.
