Mandala t-shirt design Nature's Code

For one design I’m sketching for weeks, while the next one seems to appear on paper ‘without any effort’, as if it comes from a different dimension. And so it was with this new design ‘Nature’s Code’. A design that is inspired by the Fibonacci series, a natural pattern that can be found everywhere in nature that is also known to be the source of everything. This resulted in this special t-shirt design, which for me is about living / being more connected.


I am Tessa Smits, a Dutch artist & writer. I feel deeply connected with the sacred geometry, mandalas and ancient shapes & symbols. In addition to the paintings, I also create unique hand-drawn tattoo designs for my own clothing line. I work together with Spreadshirt, a company that I have chosen because of their good quality, 30-day return guarantee and secure payment with Paypall or CreditCard.
