Now merge all of your layers together, so that you only have one layer. This is what my random brushing looks like:

Size it up to whatever size you would like it, then brush a few blobs onto the background. Get out one of the standard soft brushes that come with Photoshop. It’s probably best to use a very large document size for this tutorial, but I’ll just use a small size for the sake of learning. This is up to you, do you want a very large brush that you can size down every time you want to use it? Or do you want a brush around 200 pixels in size so that it’s ready for use whenever you want to use it in a small document. First of all, as usual, create a new document in Photoshop.
