There are a few things you need before starting to make a box outline in Photoshop. First, you’ll need to create a basic shape for your box. This can be anything from a simple rectangle to an ellipse. Next, you’ll need to add some basic details to your box. You can add text, images, or even shapes. Finally, you’ll want to add some borders around your box. This can be anything from a simple line to a solid color border. Once you’ve completed all of these steps, your box outline will be complete!
