I open something with paint and then I do crop and copy the area. Then I open up another document and paste it. Now I am trying to blend it in. I think I can use layers. Create a new layer, then add a layer mask. Then, at least that's how I have seen it online, I can use the brush tool to make the background reappear around the letters ( letters in my case). But this does not work. The brush only paints it in the background color. I can't figure out how to do this.
