Saw this the other night so we thought we would try it.
Take your Cuttlebug embossing folder and open up

Next get your ink pad, and if you have one a brayer....don't worry if you have no brayer you can apply the inkpad direct though the best result is achieved with the brayer.

One side of your embossing folder is rough and the other is smooth. Apply the ink to the smooth side with the indentations, put your card in the folder and run it through your machine. The effect is brilliant.

Clean your embossing folder with a baby wipe.

We've been playing about with it in the shop and we have tried lots of different coloured inkpads and the result is amazing. Highly recommend using the Big and Juicy rainbow pad with a brayer.
