Myah Tasker's Beads of Courage necklace is so long it doesn't matter how many times it's wound around her neck, it keeps slipping down her shoulder.
Each time it happens, her mother, Denise, interrupts the photoshoot and tells her to fix them so the picture is perfect.
Myah, 6, of Dunedin, is one of the three young stars of this year's Child Cancer Foundation appeal, and yesterday the children got a taste of what being famous would be like.
Emilie Johns, 4, of Point Wells, Rodney, has been practising walking with a book balanced on her head.
"That's what she thought being a model would be like," her mother, Kerri, joked.
