Hobbies can help you relax, and give you a sense of accomplishment. And celebrities, including Kate Middleton, can get just as much joy from hobbies as those less royal.

Middleton’s husband Prince William recently shared her little secret while presenting illustrator Johanna Basford with and OBE—Officer of the Most Excellent Order of the British Empire Buckingham Palace—award for services to art and entrepreneurship. Basford is the illustrator behind “Secret Garden,” an adult coloring book that the Duke of Cambridge said his wife loves.
“I think we’ve just seen the coloring community flourish. And Prince William actually said that his wife likes to color in the Secret Garden, which was really sweet,” Basford told the Press Association.
The best part of all of this? You, too, can spend your days doodling in the same book that brings the Duchess of Cambridge joy—and it’s going to cost you less than $10.

Basford also shared with The Telegraph that she’s working on another coloring book, this time featuring castle scenes.

“I’m working on a new book just now and it’s set in a castle, funnily enough, so I will definitely try to remember everything,” the author said. “I’m sure little snippets of today will feature in the book. I love all the really ornate picture frames and all the beautiful sculptures, and the candelabras are just stunning.”
Fingers crossed we someday see a coloring book featuring the Duchess herself. We’d also settle for a book highlighting her impeccable outfits.
