I coloured this mandala page a few months ago. I wasn’t sure about the colours at first, but it has grown on me. The design is from my kids’ book, Magic Mandalas 2 (which of course isn’t just for children!), and I coloured it in green and pink using Copic sketch markers and Prismacolor pencils.
You can see fifty of the designs in Magic Mandalas 2 here, and the book is for sale in paperback from Amazon.
