Now switch back to the layers palette and double click the FX icon to edit the layer style. In the style settings, change the inner glow color to white. (Note: If you use this effect with a different background, you will want the inner glow color to match the background.)
Adjust the size and opacity of the inner glow to your liking. This just softens the edges of the stamp and makes the imperfections more defined. I found that size of 2 and opacity of 80 worked well on my image. Toggle the Inner glow checkbox off and on to see the difference with and without it. Click OK when you are satisfied with the inner glow settings.
