As it happens, my niece will turn 14 this year and I usually make my nieces cards and corresponding kits that teach the girls new the new model. So I did a hybrid - a waterfall card using supplies from Vicki Stegall, AASPN, SoMaDesign, DutchDiva2, ValC. I made a short vid of the card in action https://www.youtube.com/watch?v=CABsn4tv3Rc

My physical cards are never very elegant since my goal is usually to make a model my nieces can follow - I specifically looked for products I could convert to black and white and color with markers.
