Clean the jar using a cotton ball soaked in rubbing alcohol.
While the jar is drying, cut a heart from the vinyl (I printed a heart from the computer and traced it onto the vinyl. If you don't have any vinyl, place painter's tape to the back of the heart.)
Once the jar is dry, add the heart.
Spray with white spray paint and allow to dry.
Using a paint brush, cover the jar with Mod Podge.
Sprinkle the glitter over the Mod Podge and shake off the excess.
Allow the jar to dry for about 24 hours.
Spray the jar with clear acrylic sealer and let dry for about 12 hours or until no longer sticky to the touch.
