3x5" index cards, mandalas in gellyroll
These are collaborations with my daughter (12) where we each started a mandala and then added something and kept passing them back and forth.
Drawing mandalas is about focusing only on the lines, the paper, the pen. It's all about the lines. My suggestion is to work in pen or marker, no erasing, no goal of perfection. This lets you keep going and not stop to change and fix. If there's a line you don't care for, just incorporate it into something else (make a line into an arrow, a plus sign, a square, for example). To make a circle, draw it around and around a bunch of times. It all evens out into a quasi-circle.
