Here are the 4 styles:
Card 2a - this has the banner from Close To My Heart Cricut cartridge Artiste and the circles are cut from Art Philosophy. The stamps are C1619 So Many Smiles and B1449 Oodles of Doodles.
On all the cards I used The thin 3D foam tape. I don't make things "stand out" too much because it requires special postage to be added otherwise your card will be chewed up in the post office machines. If you are in doubt, take a card in an envelope to your local post office. They have a slot that is about 1/4 inch and if the card fits through it, it will go well. If not, you need to add postage to your card before mailing.
