Katie, a Brighton-based illustrator and author, said:
"I spent far too much time on trains last year. Up to twelve hours a week were taken up with just staring out the window, flicking through newspapers or on my work phone.
"It didn't feel very productive and I'd feel drained by the end of the long journey.
"I wanted to spend the time more creatively, but couldn't exactly take over the carriage with watercolours and painting equipment!
"I had a small digital tablet and decided to download an app to do some drawing and it sort of took off.
"Before I knew it I'd written a story and was working towards illustrating a full book."
Katie initially wrote and illustrated her first book I Want to be Red
, a story about a little dragon that wants to be a grown up, just for her two children Finley (12)
and Darcy (7).
However, during 'lockdown' she took the step to independently publish the story.
"My kids were so supportive. I'd come home with a sketch and they'd give me feedback and ideas how to improve it.
"They were really a big part of the process, so naturally they love the story.
"Since we've been in lockdown they haven't stopped pestering me to publish it and with the extra time I've finally been able to make it a priority.
"Now it's actually published, I really hope more children get to enjoy the story and perhaps more people will be inspired to create on their commute - it might make going back to the "daily grind" after lockdown a bit more fun!"
