Loved all the cards and the variety of styles. A couple of things kept me from rating them 5 stars: 1) Although the Circular Heart Pop up card is my favorite, when completed it is too thick to mail, making it better for a decoration than a greeting card. 2) I do wish that the cards came with envelope templates to match the size of the completed cards. It would be the finishing touch to a perfect project. Instead I have to either make a custom envelope or try to find an envelope to fit the size.
