I used the PKS-11 Igloo stamp set. The penguin was created using the Owl Builder punch (just cut off the tufts at the top of the head and use the small oval cut in half for flippers). It's been a long time since I created a Sliding Pop Up card. If you would like to tackle this style card, check out my step by step tutorial HERE. I did modify this card a little for double pop up. The wrap is 2-1/2" wide instead of 1-1/2".
