Colouring and Printing This One

Colour the water last and lightly, in one pale blue over everything. It ties a very busy page together and stops the reef and the animals competing.

The drawing is a tall portrait image at print resolution, so it fits A4 and US Letter without cropping. If your printer offers a “Fit to page” or “Scale to fit” option, use it. Plain paper is fine for crayons and coloured pencils; if your child works in felt tips, print on the heaviest paper your printer takes and put a spare sheet underneath, because markers go through ordinary 80gsm paper and mark the table.

Printing two copies is worth it. The second is for when the first goes wrong, which prevents a surprising amount of upset. You are welcome to print this sheet as many times as you like for your own family, class or party. Please just link back to this page rather than re-hosting the file elsewhere or selling it.
