Start, by painting the pendant with white. Give it several coats and let it dry. While your pendant is drying, coat your fabric with Mod Podge Matte.
Paint Mod Podge Matte on top of your pendant. Smooth the fabric down over the pendant. If Mod Podge comes out the sides, just wipe it away with your paintbrush.
Cut the fabric off very closely around the pendant. If some of the edges are coming up, just reapplying the Mod Podge, smooth down and let it dry. Use a pin to push through the pendant hole and move it around to make it wider.
Now add craft glue in the shape of the heart on pendant. Then sprinkle the microbeads onto the glue.
Let the glue dry for several hours and then tap off the excess microbeads. Finally, add the chain to the pendant.
