I want to create really big image, but I don’t want to start this from scratch. I want to just use a small image, say, 200px x 200px, and I want to somehow make it as big as 2000px x 2000px or bigger. Obviously, if I just stretch this out, I see rough edges. How can I make this image bigger AND make its texture smooth? Blur tool? Combination of blur tool and sharp tool (in Photoshop)?
