Caardvark's June challenge is to use embossing on a card. For my submission, I stamped the "celebrate" sentiment in different colored inks, and put clear embossing powder on while it was still wet. I prefer this over using colored powders, because I get a wider range of colors for a cheaper price, and I don't have to be as precise. The little stray molecules of powder that are sometimes left behind are a lot less obvious with clear!
Oh yea- I forgot to mention- I used good ol' colored pencils for the rainbow gradient.
