Fold the Bristol board in half. Choose a sheet of TOGA paper and glue it to the front page of the folded card then flatten down firmly.
Trace a 15cm high x 9cm wide oval on the front cover, near the top and centred on the width.
Sort the buttons by size. Arrange the biggest ones on the oval and glue them down. Then arrange and glue the medium-sized buttons so they overlap the big ones and touch each other. Lastly, glue the small buttons on top.
Leave to dry for 1 hour.
Make the word “Easter” below the egg by gluing on cardboard letters, then place a heavy book (a big dictionary or similar) on top of the card to make sure the glue takes a good hold.
