This is a beautiful stamp set, Scenic Season #115354, from the Stampin' Up! 2010-2011 Idea Book & Catalog, page 36, that allows you to make an easy and elegant Christmas card.  Just stamp the trees and a greeting, add a little Dazzling Diamonds Glitter and maybe a snowflake from the die cut Northern Frost #120901 in the corner.  Layer on whatever cardstock colors you select.  I used Night of Navy and Cherry Cobbler.
