I stamped the image six times on vellum paper with Versamark ink and embossed with white detail embossing powder which you can find at the SweetStamps store - a link is provided below. This really worked well for me, I used the embossing bag before stamping, poured on the powder and tapped it off and had no unwanted powder where it didn't belong. I was impressed with it!
After heat embossing I colored the section of the image that would show after stacking on the back side of the image and lightly embossed on the front side using a metal ball stylus keeping away from the embossed lines, a folded paper towel was used for cushion. The embossing does lighten the color so I stayed away from the darkest areas you see in the finished project. I cut a little more off the image as I stacked the layers.
2 Elmer's permanent glue spots and Fiskars white adhesive tabs were used to attach the layers together. The glue spots gave it just the right amount of height and two of them were also used to attach to the card. The white tab are flat like tape and one was placed under the rose center to brighten up the yellows.
