Pop up Money Slot how to Using Balloon Popup Thinlit
This is the inside of the card I posted yesterday.
YOu can make any pop up by making a rectagular tube. The left shows you how. I made this one 4x41/2 inches but you could make it shorter or taller depending on what you want. I scored it at 1 1/4, 2 1/4, and 3 1/2. When you put glue on the top and bottom panel in the front and put it in the fold of your card, it makes an automatic popup like this.
I love the little slit or balloon stem die from Stampin' Up's Balloon Popup Thinlits (Occasion catalog) because it makes the perfect little slit for money or a check.
