I made this one for my niece whose birthday is next month. The heart is made of shrink plastic. I added a jump ring and a string to make a necklace. I punched a hole behind the heart through only one layer and pulled the cord through. I used double sided tape to attach the stamped layer to the front of the card to ensure the string did not get glued in place. When she receives the card she can simply peel off the heart (foam tape) and pull through the string and her necklace is ready to wear! Pretty happy with how well that worked out.
