Here's a card using the Dove of Peace stamp. It's lots of fun to color - along the same idea of the adult coloring books that are so popular now. As this color scheme shows, this stamp doesn't have to be just for Christmas.
I embossed the image on vellum, then colored on the back with Stampin' Write markers for a stained glass effect. I used the Curvy Corner Trio punch on the edges of the Marina Mist layer and the Corner Rounder punch on the card base.
