Those two cards were demonstrated by Shelli Gardner at Leadership. She showed us how to use the new ink pads directly on the cardstock to create a background and then overstamp images from the Oh, Hello stamp set. I couldn't resist adding some Dazzling Details around the rectangle and oval to give the card a little extra pop.
