For my card, I used a Shimmering Resist Background for the main green panel (August 2008 issue of the Technique Junkie Newsletter -- also on CD6). This is a VERY shimmery card in-person -- I had a hard time capturing the shimmer. A little slice of it is on the right so that you can see how pretty it is. My focal image was smaller than Margaret's so I had to add an extra black layer (under the seahorse) and I also had to change where the embellishments were because of the scale of my image. For comparison, here is Margaret's card:
I think that I haven't done her justice! When I see the cards side-by-side like this, Margaret's certainly is far superior. Beautiful work, Margaret!
