Emily Browning header tutorial

I'm looking for a header tutorial. It's somewhere here on LJ but I just can't find it!
The background is light blue with clouds, has an image of emily browning & a large moon just above her head.
if that's not really descriptive enough, the lovely ullaaa has a similar version of the header here. (no, she doesn't know where the tut is either)

So, if you've seen this tut please let me know! :)
