I had a request for a tutorial on this type of card. Reba made one and posted it on the MTC forum here. She included a file to show how she designed the card.
here) to make a similar card.
Make an inner shadow of this piece. I make it just a little smaller than the actual front of the card so that I have a little fudge room when placing it inside. (I think Reba made it the same size, either way will work but it does need to be made now before going further with the design of the card.) I moved the layer below the card base and locked it.
Hope that helps if you want to make this type of card. Not all images can be used like this, you need to start with a stencil-like image for the part that will be cut out.
