Zenline is a new colouring activity book concept with a difference.Instead of colouring in between the lines, trace the lines themselves with a black pen and discover a new zen activity to occupy your mind and hands.Once the drawings are completed, readers are then free to add their own colours, or leave their artworks in striking monochrome.Accompanied by thoughtful quotes to consider while you draw, these books offer a mindful break from the busy and stressful world, and the perfect antidote to doom-scrolling.
