You will use Mod Podge to glue down the shape to the surface. Then you're going to let that dry, and add a few more layers of Mod Podge as your finish. Mod Podge essentially acts as a glue, sealer, and finish in a craft project.

What does Modge podge do?

Mod Podge can be used as a glue to adhere fabric, paper and other porous materials to nearly any surface. It holds tight and dries clear. It can be used as a sealer that protects acrylic paint, decoupage, stain, fabrics and much more.

What is the best way to use Modge podge?

When applying Mod Podge over a design, apply one layer of the Mod Podge with side-to-side brush strokes. Allow that coat to dry for 20 minutes or so before applying another even layer of Mod Podge in up-and-down strokes. I have found that this process results in the smoothest possible finished surface.
