Zentangle® is such a wonderful practice. Tangle patterns seem to find their way into most of my art. I also use it as a warm up exercise when I get in the studio and feel a little stumped as to where to begin.
I look forward to each new Zentangle book that is published. I just received copies of 'Zentangle 8' and 'Joy of Zentangle', ...... fun and fabulous books. Both books also feature the work of some great Zentangle artists and CZT's.
One of my alphabet Zentangle tiles is in both books, 'S' for Shepard...notice the tiny eye in the top curve of the 'S'?
