making elements look like a sticker

I've been asked on how I made my "follow me " tag in my sidebar look like a sticker that is peeling off. Well here ya go.

First I typed out my text. Then I clicked on the little symbol in the layers pallette,"fx" and chose the option 'color overlay'.
With that layer selected, I clicked CTRL-L to get a new layer. (CTRL just makes the new layer go underneath the active or selected layer).
Now I expand the marching ants(the selection) by chosing SELECT-MODIFY-EXPAND. Chose your preffered size. Now chose the paint brush tool. Chose the color white and fill the inside of the marching ants.
Now you need to add a drop shadow to make it look like the sticker is being peeled off. I warp the drop shadow to my liking.
