The "intermediate" card used Perfect Pearls pigment powder. The small holly images were stamped on the red CD envelope with Versamark and then brushed with gold Perfect Pearls for a pretty, subtle background. The circular greeting was done the same way on a green square of cardstock. The poinsettia is an embellishment I found at Michael's which fit perfectly in the center. The envelope was then layered onto the green square card and edged with gold Krylon pen.
The more advanced card was a shaker card. The black CD envelope was again stamped with Versamark and brushed with interference Perfect Pearls and outlined with gold pen. The snowman was stamped on a white square and colored with watercolor pencils. It was then inserted into the CD envelope with irridescent confetti added. The key to this easy shaker card is adding a dimensional sticky strip the entire width of the envelope at the bottom (the flap must be at the bottom). This gives a little bit more room inside the envelope for the contents to move about. The flap is then glued shut and the envelope layered onto the green square card.
These envelopes make super easy and cute cards. I had no idea that they came in colors other than white! And, they are super cheap, especially if you get the kind with no adhesive on the envelope flaps.
