Well, I made my own rainbows, and also have created my own wings, however there are Wing brushes, that can be used with either Photoshope or Paint Shop Pro.
And you might want to develop them at 2x the size like 1200 x 300, and then when it's all done and you're flattening it, you can shrink the image size.Originally Posted by icklemiss21
I do mine at 550 wide and 134 tall but you are allowed up to 600 wide and 150 tall
