Australian florist Chelsea Shiels started making flower crowns to hide a scar on her forehead. Now, she's got customers around the world covered with ornate, jewel-laden headpieces fit for a mermaid.

Using feathers, crystals, gemstones and seashells, she assembles everything by hand and sells the pieces through her Etsy shop. Her 162,000 Instagram followers eagerly await her latest model.

"I just build it from my brain as I go," she said. "I never do two designs the same."
