Lately I have been playing with some of the tangles that show up in a lot of introductory classes, and are great foundations for learning the practice of the Zentangle Method.
It is really fun to revisit the same tangles in new ways, and I love making a mosaic that spans time, experiences, moods and locations. It is like my own little set of historical markers.
You can see how much variety there is to be had with just a few tangles, I could easily and always entertain myself, find focus and relaxation by just using these tangles.
