Create-Your-Very-Own-BOID

Paper or card, crayons or paints, sticks or stones, leftover bones - scavenge, hunt and forage for materials to make the most spectacular and original BOID the world has ever seen.

Hand your BOID creation into the Bookshop before 3.13pm on Saturday to be in with a chance of winning a signed copy of Ralph and Ceri's brand new book.

One grown up and one child winner will be announced at Ralph and Ceri's talk, 5pm, Saturday Bowling Green Stage.

Don't forget to clearly label your BOID with your name, age and mobile number.
