This quick tutorial is an extremely useful and easy way to give any object a grunge effect. Best of all you can move the grunge layer in real time until you are satisfied with the look.

1. For our example I’m going to create a rounded edge box with text inside. This tutorial is design for a white background (but don’t worry - I will explain later how to do it without a white background). On a new layer begin by using the rounded rectangle tool with the ‘fill’ option selected with any color you like. If you use the ‘paths’ option right click it like shown and go to make selection.

2. Once your shape is filled with a color, make sure it is still selected (so it has the marquee selection like shown) and go to select>modify>contract. And use a value of around 6 pixels.

3. Once the selection is contracted, hit the ‘delete’ key on your keyboard to delete the contracted selection.
