Know that some people record their certificates by placing them in folders with love and care while some people have them framed and hang them in their offices and houses, etc. so as a creative and responsible graphic designer, it becomes your duty to ensure that you are not settling for less when it comes to the quality of the certificate, the printing or even foiling for that matter. Lastly, present your designs in a nice mock-up presentation to your clients so that they can visualize how the certificates will look in real life before getting to the next step.
