The Pop-Up Elements Narrow Die-namics will give stability to popped up elements on the inside of your cards giving your recipients a fun surprise! Center the center fold line with the card base fold (or other folded card stock), and cut, leaving behind a platform on which to adhere stamped or die-cut elements. Simply reverse the fold of the die cut element, so that when the card is opened, the element(s) pop up. The Pop-Up Elements Narrow set includes five pop-ups measuring: 1/2” x 4”, 1/2” x 3 1/2”, 1/2” x 3”, 1/2” x 2 1/2”, 1/2” x 2”. American made steel dies. Die-namics dies work with most tabletop die cutting machines such as the Big Shot & Cuttlebug.
