I like this picture very much:
But it bothers me (and others) that the bottom rose is so close to the edge of the picture. Especially when printed and matted, it's not acceptable. Could someone tell me step by step how I could clone a bit of border onto the picture in PS? I know I'd have to make a bigger canvas (at least at the bottom) and then extend the bottom of the image, but I'm not sure how to do that and keep the aspect/dimensions of the pic. Thanks to anyone who can give me a hand with this one.
