How to merge 2 skies?

[GraphicHero]

I have a picture I'll be using for the design of a cover. Since the shape of the picture isn't vertical I'll need to add a more sky from another picture.... How do I go about this? I have looked for tutorials but haven't found any explaining this.

Try content aware fill maybe?

Hi GH, I don't think I would try to add another sky............instead, I would remove the current one and replace it with a larger one to fill the canvas.

Here are a few tuts on the matter........
