I always discover something new at the Edinburgh International Book Festival. But not usually about my own books!

This year, however, I was astonished to discover something new about the creative process behind The Treasure of the Loch Ness Monster.

I did an event with the lovely Sara Sheridan about our two different picture books based on the same monster – Nessie.

We both intended to start the event with a short visual presentation about how our books were created. But my writing process is mostly scribbles on bits of paper, which isn’t that compelling visually. So I asked the illustrator of the Treasure of the Loch Ness Monster, the amazing Nataša Ilinčić, if she had any pictures of her creative process I could show, because her process is obviously more visual than mine.

I expected a few sketches of Nessie’s evolution, as Nata worked the shape and character of the monster, and perhaps some sketches of her background research. She did send those, and they were fantastic.

But she also sent a few photos which just blew my mind.

I discovered that when she was sketching the treasure chamber under Castle Urquhart, she actually built a 3D paper model of the chamber!

Look…

She didn’t just sketch the treasure chamber. She MADE it. Then she put it in front of a window to get the light and the perspective right, in the sketch, then in the illustration.

Isn’t that amazing? Isn’t that just so… magical? But also, really practical!

I feel overwhelmingly privileged that Nata put so much effort and thought and creativity into just one page of our book!

So, that’s what I learnt from this year’s book festival. Nataša Ilinčić is practical and magical and amazing. And we can never know how much work goes on behind the scenes of a picture or a scene or a chapter of a book…

I’m delighted to let you know that Nataša is currently working on the illustrations for our next book together: The Legend of the First Unicorn. I wonder what practical magic she’s building in her studio right now?
