This is a technique that I've used in my recent mini album project. It's such an easy technique to create a distress look on your projects especially non porous surfaces such as acrylics, transparencies etc.
Just simple cut out some pieces of Magic Mesh in your desired colours (preferably colours that works well with your project to create the distress look) and randomly paste them all around the edges of the project. Use some acrylic paint to paint part of the Magic Mesh to slightly cover it's edges and blend it with the project.
I'll be uploading the completed project soon. Try this easy distressing technique in your next project.
