How to Create a Holographic Lighted Fairy Jar: The fairy is magical in this cute project. What gives her the twinkle? It's a holographic sheet (curled up inside the jar) that causes the lights to look like stars when they are behind it. The firefly lights give it the magic! The jar was sprayed with Krylon Sea Glass Spray Paint. Adorable! Our team is always happy to help you find all you need for your next project. We'd love to see you!
