I'm using the distressed enamel technique Tim Holtz demonstrates in his 2007 Day 7 tag.
Apply shabby shutters Distress Ink directly on to card (I know my card is already wrinkled, but no worries, more distressed appearance). Coat entire surface with clear embossing powder (ep). Tim says to use regular ep, but I don't have any, so I'm using detail ep. Tim flicks the back of his tag to remove some of the ep, since I have the detail ep and it gives a better coating, I tapped my fingers over the surface to remove some of the ep.Then heat with heat tool.
Use blending tool to cover entire surface with vintage photo Distress Ink, press hard to get this ink between the ep.
