I have a Wizard and have not tried this, but with my understanding of how the Wizard works I think this is how you would do it .
Stacy is demonstrating the CB embossing folder in the Wizard.
How-to Videos - Spellbinders
scroll down to Cuttlebug dies and embossing folders
You need the Blue charm kit plate . It is thinner than the white master mat
Eliminate the tan mat ( it is only used for space) and put the chipboard with the shape cut out over the card front
You only need one piece of chipboard or cereal box with the shape cut out . You don't need the positive shapes for just an un-embossed space
Hope this helps
