Click around to make pixel art, left and right keys to change the color, c to clear, and up and down keys to make the color brighter or darker. I took a screenshot of the thumbnail and then edited it in Photos, then I uploaded the picture as a background. If you have a Windows like me you can do the same.
Grid snapping script from Scratch Tutorials on YouTube. Pixel art thumbnail by myself using this project. Loved and faved by @cheddargirl*, thank you! No eraser tool, so you have to use a similar color to cover it up. Sorry.
