These are so addicting. Once you start, you can't quit. I may need therapy to get me out of this. It's these Micron pens. They are so fine and you can get really good detail. Dots, Circles, Wavy Lines..you just make it up as you go along. Go to www.zentangle.com for lots of ideas. My grand daughter, Jessie, is so good at these. So I dedicated this one to her.
