Note: This tutorial is done by Adobe Photoshop 7.0

1. Open any two images one being a box and another a sticker, in my case I have chosen this box and a starbucks" sticker. You can save them in your PC and work with it.

2. Next bring the sticker onto the box, by selecting Elliptical Marquee Tool (M)  Make sure the Anti-aliased is ticked. That is for smoother cut. While selescting hold the Shift so that you can make a perfect circle.

3. Select the Layer1 and choose from menu Edit > Free Transform (Ctrl + T). Make the size smaller so that it looks like a sticker and align it as shown to the left. Make sure the 2 S of Starbucks is aligned parellel to box"s edge. Next press and the Move Tool (V)  and apply the effect.

4. Select the Polygonal Lasso Tool (L)  and select the half of the Layer 1 as shown to the left. Next Edit > Cut (Ctrl+X) and Edit > Paste (Ctrl+V) to the new layer.

By now your layers should look like this:

5. Select Layer 2 and go to Edit > Free Transform (Ctrl+T) right click on the image while Free Transorm is selected and choose Distort from the Pop up menu.

Now try to make it look as close as to the image to the left. You need to take into account the angles of the box, so that your sticker looks more real.

6. Done with the Step five? Now the same thing for Layer 1. Edit > Free Transform, then right click and choose Distort. Make as close as possible.

7. And finally you have it here. The Sturbucks delivery to you in a large box:)
