I teach a course at the University of Regina in which students learn how to use visual art, dance, drama, movement, voice and play with children in the classroom. I introduced Zentangle last week as part of a process exercise in which they explored movement of line. We started with string.
First in groups they wrapped string around themselves to become a human string art piece. Next they cut the string into smaller pieces and they each created a string line drawing on a sheet of paper.
Lastly, they did a Zentangle drawing on a 4" by 4" piece of paper. Zentangle drawings are small ink and or pencil doodles that are relaxing and fun to make. I use them in my Art Therapy practice for clients who want to have a creative way to relax and focus.
