If you're in New Zealand's screen industry, the answer to the question "Where did you get that hat?" is often milliner Hayley May. Hayley's meticulous hat and glove making skills have been put to the test on many screen projects over the years - on Xena Warrior Princess and Lord of the rings, then later Cowboy Bebop and Mulan. And when there's a gap in the film schedule, she tops up the bank balance by crafting items to sell to the public. These include her trademark reversible sunhats.
