I originally published this book in November 2016, under my previous author name Tigerlynx. In the second edition, the author name has changed and the back matter has been updated. The designs themselves are still the same as before.
Happy Mandalas has 30 original cute cartoon mandala designs, and is great for both adults and older kids. Themes include animals, flowers, Christmas, Halloween, Easter, monsters, space, cars and more! Most have a medium difficulty level, with a few that are more or less detailed. You can see all the pages here.
