Start with one of Creative Memories digital pages that has a torn edge. Select the edge, and copy it, then paste the edge. You will then have two of the same thing. Next change the color of one edge to white (or the color of your choice). Use the opacity tool to make it lighter. Then change the color of the second one to any paper of your choice. Then layer the two with the white one on the bottom and the colored paper on top. This makes a wonderful torn edge and very easy to create.
This page was created using Earthy Serenity Predesigned pages.
You can then save the torn edge by right clicking on the edge and choosing Save Selection to save it in your My Scrapbooking Stuff.
