Here are my 5 easy steps recommendations:
1. Create an account on Canva here: Canva Home Page
2. Learn the basic navigation from Canva’s Design School: Canva Tutorials
3. Choose what design elements you want to use in your design. If you are using your own photos, videos, or music, then upload those to your account.
4. Personal Variations.
~ Replace, keep or change the existing photos, backgrounds, and text with yours.
~ You can also replace existing photos with your own videos.
~ You can add or replace audio and music, with yours or ones out of Canva’s database.
~ Change colors and fonts to those of your own choice.
5. Download your work as JPEG photos, PNG, PDF or MP4 video files, as required, and upload to your media or marketplace.
