You thought you did a good job screening, but your last nanny turned out to be a nut. The husband and wife duo behind Otto & Lulu may not be able to help you find Mary Poppins, but they do know a thing about screening: Silk-screening, that is. Printed and dyed in a sprawling Port Richmond workspace, their line of tees is modern and fresh. Each shirt is adorned with bold images like astronauts, dinosaurs, and insects; even angels and roses are given a gutsy, updated treatment. Inky smudges add to the charm. It’s all a little offbeat, a smidge quirky, and totally unexpected. Qualities you definitely don’t want in your next nanny.
