I recently bought the book One Zentangle a Day from amazon and I’ve found it a lovely and practical introduction into the art of zentangles. This is a recently developed technique where you draw repetitive strokes over and over again, adding shading and highlights to form a patterned tile. These tiles can be shaped to create a greater picture or form. Below is a starter Zentangle that I drew recently. It is a very meditative form of art, hence the zen in Zentangle.
