I started with the main image, which was stamped in Pearlescent Poppy Brilliance Ink then embossed. The embossing was a bit uneven but as I planned to make the card quite grungy I decided to just go with it and sponged round the edges with Black Soot Distress Ink:
The background was a combination of more stamps from the Inkadinkado set, and stars sponged through a mask, all with Pearlescent Poppy again which I discovered isn't pearlescent on kraft cardstock! The greeting was created in Craft Artist 2 Professional using Retro Rock Poster font.
