I am an illustrator and fan of Zentangle - Mandala and coloring patterns, I have already sold hundreds of coloring books of Mandalas and other patterns on my account and have created 103 coloring books for my clients. Each customer receives unique Mandalas and designs that will not be sold to anyone else. The colouring books and Mandala designs sell very well. They have become the trend of the last two years. I will create 10/50/100 Amazing Zentangle and Mandala pages with RIGHTS OF COMMERCIAL USE. Resolution: 300 DPI (3400 × 23400 pixels) if you don't have time i can create the book in PDF 8.5x11 20 for dollars. you'll get a book ready to be sold on KDP Amazon or Etsy ....
