Hi! Here is my process.

Step 1
I look for an image on unsplash.com, images.google.com, pexels.com or pinterest.com.

Step 2
I edit using canva.com and madewithover.com, both available as websites and mobile apps. I use the site for Canva and the app for Over. Both Canva and Over have resize tools to ensure that your cover has the right dimensions.

Step 3
I get cool fonts from dafont.com and edit text onto the image.

Step 4
I add effects using picsart.com. I use the app.

Step 5
I export my graphics as PNG files for the best quality and upload.

I hope this guide was simple and useful. Follow me for more tips and tricks!
