"Whatever the fairy touched, no matter how mundane, turned into something beautiful and mysterious."
The illustrations are full of tiny details to explore and color, though it's also not too overwhelming. Many coloring pages have the fairy on them. Some of my favorites included a vanishing library and a chandelier room. There are also two visual lists of hidden objects that you can identify throughout the book, with a key at the end.
I used color pencils, which worked well even in the small details. The pages are double-sided, so I did try out a marker and pen to check for bleed-through, which wasn't too bad, but some of the images have a lot of open white space where it would be painfully obvious. Many of the illustrations run the spread, which creates a large two-page design, but also unfortunately means that there are illustrations running right through the gutter making them near impossible to color.
All things considered, there's a good variety in detail level and design of the images, so as long as you're on board with the fairy theme, this coloring book is definitely worth checking out. You can even color in the both sides of the removable dust jacket. There's also a to/from page at the beginning - good to remember when you're looking for that last minute gift.
