In this image, I moved the hat from the boy on the left to the boy on the right...clever. I know. First, I used the quick selection tool to select the red and blue hat. Next, I moved it onto a new layer and refined the edge. Second, I selected the blue hat in the picture on the right. I moved it to a new layer and then deleted the selection in the main image. Next, I resized the images until the blue and red hat looked about the right size. Next, I dragged that hat on the left onto the image on the right. I adjusted it and then used content aware fill to fill in some of the blank spaces around the new hat. Finally, I used the brush tool and eyedropper tool to match the color of the hat and fill in some spaces around his face.
