Book Week 2026 is almost here! Costume ideas for parents, caregivers, librarians and teachers for this year’s events.

Times are tough, so if you can make a costume from what you already have in your wardrobe, that’s perfect.

Here are a few simple Book Week 2026 Costume Ideas inspired by A Big Blue Boat, A Day on the Brine, Captain’s Cave, and A Frog’s Tale

You can add lots of quick details with paper—like a captain’s hat, a fish, a mermaid, plus a frog face mask, hands, and a lily pad.

To make a captain’s neckerchief, fold a square piece of fabric in half to form a triangle, then roll it tightly. It’s simple, quick, and looks great.
