My favourite Alcohol Ink technique is to use it on clear acetate, and then apply clear double-sided tape and foil the back. If you click on the photo below you might be able to see how the acetate glows like jewels. I used silver foil.
The Alcohol Inks I used were Cranberry, Wild Plum and Denim. I cut out a Sizzix scalloped tag die cut from acetate and used Tim Holtz's On the Edge Brackets die to create the top and bottom borders from acetate. Steel rule dies like these are best for cutting acetate. I embossed the top border with a Sizzix checkerboard embossing folder.
The card background was created by second-generation stamping the Direction of Your Dreams (Time2Fly/Uptown) in Iris StazOn over the white card front, then sponging Wilted Violet Distress Ink through the Bubble stencil.
The dragonfly is from A Stamp In the Hand and I stamped it on the front of the tag with StazOn Cotton White. A brad and some gem stones finished it off. This will make a nice graduation card for someone.
