Said in my best Dr Evil voice!! I love the effect of this technique, it really creates the sense of dimension and it is easy to do! All you need is a brown ink pad and a good white embossing powder and a nice stamp. So simply stamp your image in the brown ink (I used Frayed Burlap distress ink) then while the ink is still damp give it a little smudge. Make sure the image is dry and then re-stamp the image with an embossing ink, over the top of the smudged image, so the brown shows through. Then add the white embossing powder, heat set from behind and watch the whole design just pop out of the card!!
Simple but very effective!!
