I have used the zentagles, I call them zendellas. I teach high school beginning art, I use them in the beginning of the year when I'm teaching line. I have my student create a cool watercolor wash then draw back on top of them using a pen or sharpies of various thickness. The students must fill the whole paper 12x18 and try to exhaust every kind of line. The drawings turn out really good for their first drawing, I like to start off with more abstract things in the beginning and my students like them surprisingly!

Subject: RE: [teacherartexchange] Stuck for New Drawing Ideas--what about Zentangles?
In addition to teaching them to draw from observation, you could teach them how to use drawing and pattern-building to fill a space in a beautiful/interesting way. Zentangles are a drawing activity that helps to build confidence and promote relaxation. Anyone can learn to create beautiful Zentangles...just google it, and you will find a plethora of information. Zentangles to NOT take the place of the traditional drawing curriculum, but perhaps you would find the Zentangle concept to be a good supplement.
I'd be interested in hearing what others in our group think of Zentangles...I have not used them in my teaching yet, but I think I will next year. (I teach elementary.)
