This technique is called faux tearing. It's meant to look like you tore some card stock and layered it. But what you actually do is tear some scrap paper, lay it down on your good card stock and then stamp. When you lift the scrap paper it looks like you tore the card stock. It helps if you make sure that some of the image is on the scrap paper. This saves you some card stock because your only using one sheet instead of two. Cassie Thelan demonstrated this technique and made this card.
