While searching for free printables for my daughter, I just found a great page of free printable "polar" graph paper, perfect for starting your own mandalas. Try drawing designs or doodles within each cell - or even just simple lines - and watch for patterns to appear! Polar graph paper is great for kids, too - even if they don't want to draw a mandala, they can color in the cells and learn about patterns and geometry. Now I want a tablet of this stuff - super geeky!
I will be back creating mandalas for you all, just having a rough patch. I'll be using this polar graph paper myself to get over my artist's block. Enjoy, and as always, pass it on!
