I white heat-embossed the roses on a piece of vellum, just using scrap paper to create masks, so I could create a bouquet. I then colored them in with Zig Real Brush markers, which I scribbled onto a craft mat, and mixed with a bit of Perfect Pearls, and a bit of water. I just used a regular paint brush to color them. The frame is die-cut, with the vellum attached to the back, and the whole piece attached to the card base with some foam adhesive.
