I'm looking to make a tiled image that handles the body of the entire blog, which is basically a custom field with jagged edges (parchment). But the top image I want to use is also a part of the field, with a top jagged edge, to sit behind the blog's title image.
That is, I want to make:
<top image in background>
<repeating image that marries to above>
How do I do this?
