Following Linda's instructions http://www.lindart.blogspot.com/ I painted on matte coated cardstock and gloss cardstock. I then used clear embossing ink and clear embossing powder. I painted over with another color of acrylic. I covered with white cardstock and then ironed over it. I first tried with a craft iron. I found that unsatisfactory as it did not heat up enough. I then dragged out my "real" iron and got much better results. The "negative" image transferred and you can see that effect above.
