"I tell people, 'I make food-themed accessories' and boom – they get it," says Jenny Lennick.

For the San Francisco-based artist and entrepreneur that niche underpins a thriving retail business.

The 39-year-old runs a small Californian accessories brand called Jenny Lemons. It is best known for its quirky, colourful hair claw clips, made from a plant-based alternative to conventional, petroleum plastic.

She designs the products, selling them directly on her website, and wholesale to around 1,500 independent retail stores in the US and internationally. And all the hair clips are themed around food.

If you want to wear rainbow chard, a sardine tin, or a TV dinner in your hair, Lennick has a clip for that, though the company's bestseller is a strawberry.
