Above is the notealope closed. The top flap tucks into the little diamond behind the image. For this part, I used the House Mouse Party Mouse image.
The photo above shows the notealope open. The image I used inside is House Mouse Mice Cream Celebration. The green piece is folded up from the bottom and stamped with the sentiment. A gift card can be tucked inside the folded piece.
Dawn Griffith (Dawn's Stampin' Studio) has an excellent video on how to make this card and envelope in one. It's surprisingly easy and is made from one 11" square sheet of designer paper.
