Monday's "Try a New Technique" challenge was Debossing Vellum....sort of similar to dry embossing. I used the "Infinite Goodness" stamp set. The berries were stamped on plain vellum with black Staz-On ink. Once the ink is dry, you turn the piece over and, using a stylus, mark in the areas you want accented in white, or the parts you want raised on the front side. I debossed the dragonfly on velum cardstock. Not too much difference but because of the thickness of the paper, I think the white shows up better.
