Hi- this card was made by Donna Mato,i my Stampin Up demonstrator. I am always fascinated by cards that have unique folds. I will have to try some myself. I like the spring colors and since Easter is on its way I thought I would post this card.
To make the card you just fold the top of your card diagonally, then add something in the corner (in this card it is the green tag and greeting) mounted on foam tape to hold the folded part of the card up.
