This is my first time doing this and so had to try a couple different things to get an effective shaker. In the end, I took a piece of Lawn Fawn diecut plastic packaging (I keep the dies in a tiny ziplock bag with the matching stamps), folded it in half, added adhesive to the edges, put my hearts in the center and then sealed the edges. I adhered this over the sentiment panel and then added the top layer using dimensional adhesive.
