Cut out the printed squares and layer them on top of each other with foam pads or silicone glue for a 3D effect. Align them so that the outer edge of each square is at a slight angle but the image itself is straight.
TIP: You may like to practice aligning the layers on top of each other to make sure you’re happy with the angle BEFORE applying the glue/foam pads. Use the image below as your guideline to line up the layer on top.
