I know I am using vellum butterflies so often, but you must admit that they are really awesome!
For fusion card challenge I took sketch a and from photo I used green colours.
My card is easy, I cut on my Silhouette Cameo vellum butterfly and stamped over it Tim Holz stamp with text. Background is also easy, I cut out square from card base and square from paper. I again use Tim Holz stamp and three Distress inks. And here it is.
