Step 8 Select background shape the same way you selected the paper ball in Step 3. Perform a right click > Select Inverse. Select the Eraser tool (E) with a white foreground and black background and erase the shoulders and any other parts you don’t want to find in the final piece.
Step 9 Open up the image of your paper ball and drag the layer into your main document. Invert the paper texture and position the layer at the bottom. Select the Marquee tool (M) and on the paper ball right click > Free Transform. Position the ball so it peeks out behind the model. Create additional balls using copy and paste and place them on the canvas until you have a texture like the one shown above.
Step 10 Using the same masking technique as in Step 8, you can add texture on the layers behind your model. I’ve used the same circle to mask in the paper ball texture. Using masks in this way is a great way to add depth to 2D pieces you’ve created.
Step 11 Using the Pen tool (P), create some shapes that complement the flow of the piece. This is a great opportunity to add a splash of colour as at the moment the piece is pretty much black and white. Move the layer so it’s just below the circles you created at the beginning.
