From original poster: Zentangled Garden. This is my second zentangle. I like drawing normal objects and scenes then putting a zentangle design within them. Can you see my little frog behind the flowers?
Positive and negative shapes. My Zentangle hummingbird. This is an example for my students' project. This can be use for several concepts: positive / negative space, reflection, line and shape, etc. I did this project with my grade students.
