Peeling Sticker Effect

First, you want to start with your object on it’s own layer. If you need help getting your object on it’s own layer

Add a background layer by holding Ctrl + Alt and clicking on the New Layer button at the bottom of the Layers Palette F7. Press D to select the default colors and press Ctrl + Backspace to fill with white.

Double-click on your object’s layer in the area to the right of the name. This will bring up the Layer Style dialog box. Click on Stroke at the bottom of the list.

Set the Stroke size to something thick for your object, in this case I’m using 6-pixels. Click on the Color box and change the Stroke Color to white.

Click on the Outer Glow Style in the Layer Styles list. Change the Blend Mode to Normal. Change the color to black.

Adjust the Size and Spread until you get a nice, soft outline. In this case, I’m using a Size of 9-px and Spread of 35%.

Move on to the Drop Shadow Style in the Layer Styles list. Adjust the Angle to 90° and increase the Distance slightly 6-px.

Press Ctrl + T to bring up your Transform bounding box. Before you do ANYTHING, right-click in the box and choose Warp.

Now click-and-drag the box from the lower-right corner up slightly.

Press the Return (number-pad Enter) to apply the transformation.

Create a New Layer Ctrl + Shift + N above your object’s layer. Then press Ctrl + Alt + G to create a create a new Clipping Mask.

Set the Layer Mode to Screen and the Layer Opacity to around 50%.

Choose the Gradient Tool G and click on the Gradient in the Option Bar (up top) to bring up the Gradient Editor. Edit your Gradient to look something like this:

Click-and-drag your Gradient in a very small area where you thing the “bend” of your sticker should be.

It may take a few tries to get it right.

Right-click on the “f” icon in the right-side of your object Layer in the Layers Palette. When the menu appears, choose Create Layers.

You will now have a bunch of various Layers underneath your object Layer. Find the one labeled “Drop Shadow.”

Press Ctrl + T to bring up th Transform Bouncing box again. Right-click and choose Warp again.

Click-and-drag the right corner towards the right to bring the shadow “back out.”

Reduce the “Fill” on the “Drop Shadow” layer to make it a little less harsh.

And… that’s it! Feel free to change the stroke and background colors as you wish. Play around with it. Have some fun.
