The New Horizons designer series paper and On The Horizon stamp set are perfect for the Double-Time Stamping technique. The paper does most of the work. Usually, you stamp a background all over your card stock for this technique. But using this paper and a few stamps die cut with the rectangle stitched dies gives you a beautiful Double-Time Stamping technique card with very little effort.

Colors: Crumb Cake, Blackberry Bliss, Evening Evergreen
