For beginners, I will indulge you to start with Canva. It's simple to use and if doesn't stress you out. It’s easy, and even if you’ve never designed before, you’ll feel like a pro in minutes. I used it to design flyers for my cousin’s small business and people thought I hired a real designer 😂.

Canva is good. I haven't used Affinity but they say it has everything that a premium software like Photoshop has. Affinity is completely free. It even offers premium features offered by Canva.
