I understand all of that and empathize…. You are not alone.
When I first started designing my first two colouring book projects these were thoughts I kept in my mind while I was designing them. I wanted to create something that was accessible to everyone. I wanted to provide colouring books for every mood.
Sometimes one might want to colour small tiny details with fine tip pens or markers and sometimes one might just want to vibe and flow with the colours and let their mind drift into a meditative state.
