This card is super simple and could easily be replicated if one would need a lot of cards for something. I die cut a heart shaped window from a white piece of cardstock and then adhered it to a green card base. I also added a green button with some string to add a little bit more detail. I stamped a small sentiment i black ink and this card could be used for any occasion if you would just switch out the sentiment. I chose to stamp a birthday greeting since I always have use for cards like that.
