Wave texture background
I was asked how to create wave texture background that I made for one of my wallpapers. I wrote this tutorial from my answer because it might be useful for someone else. So, to start, we need horizontal stripes background. For that, we need a stripe pattern. Create new document with 4 pixels height (you can also try different size).
