This technique came from the CK site. It was so easy and cute I HAD to share!

Take a silver tab from a soda can and clean it. Using a small craft hammer, tap down any sharp spots. Take a bit of sandpaper to it and lightly rough up the surface.
Using Tweezers, coat the tab with embossing ink, then dip into embossing powder. Heat with a heat gun, repeating two times with UTEE or three times with regular powder. Let them cool and thread a ribbon through the holes.

They are WAY too cute! And you can customize the color to match your layout or just leave them silver!
