Here's a really quick card I just made using the "Stem Silhouettes" set from the Stampin' Up!® Summer Mini Catalogue (Dec07-Mar08). This is one of the sets that I just had to have. It's so elegant! I've kept it VERY simple but I think it's quite effective!
Here I've used the following:
Cardstock: Sage Shadow, Close to Cocoa
Ink: Classic Brown, Whisper White
Accessories: White grosgrain ribbon, Stamp-a-ma-jig™
