Colouring Pages/ink drawings

I remember when I was sitting on a floor in my room drawing lines, flowers and other shapes (everything black & white) and then colouring them using my all time favourite colouring pencils Bruynzeel Holland 9505 high grade (today Bruynzeel-Sakura). It was a New Year's Eve 2000. 

Today pencils are no more available at shops and this strange drawings are called Zentangle and are very popular...

My first colouring book available in Etsy shop.

Everything by hand, no computer, only paper and black ink ( sometimes with colouring pencils or markers). Time consuming, yes but how relaxing. I'm addicted to create things full of details which takes hours and require patience.
