This coloured mandala is from my Abstract Mandalas 2 Colouring Book. I coloured it in warm red and brown tones, with Tombow dual brush markers on basic printer paper.
You can get Abstract Mandalas 2 in paperback from Amazon stores worldwide. The book has 50 original mandalas, and is perfect for adults and older kids – see all the designs here.
