The technique challenge on SCS involved inking up a Cuttlebug embossing folder on the negative side (the side with the Cuttlebug logo on it) and then placing the paper in it and running it through the cuttlebug. I use mine in a regular sizzix machine and it works fine.
This is the card I made using that technique. I inked the embossing folder with blue bayou ink, and then used whisper white cardstock in that. I love how it's kind of faded looking. I'm going to try this with the other embossing folder I have with a circle pattern on it too. I only have 2...I'm a little behind in the Cuttlebug craze! :-)
