Here's one of the cards that I made with the Elephant and Rhino set from Stamp Addicts, which appeared on their afternoon show yesterday.
I have to admit that this was not my favourite card but the Presenter seemed to quite like it, so that was something.
Rather than using a masking technique, I simply stamped the elephant out 5 times and the rhino once, and coloured them in. I then glued them together in a pyramid shape and then placed in on to my base card and drew around the right hand edge. This gave me a cutting edge to get the right shape for the 'cut away' effect on the front of the card.
