I have created a new mandala template. This one has a way more useful center. Download: https://www.dropbox.com/s/bcevwfh4704j83o/mandalaTemplateNew.pdf?dl=0
So, I guess the second prototype of the template is good enough for sharing, so if you want to try it out yourself, just download the template here: https://drive.google.com/file/d/0ByGAi4hoZRlwYVNnVU14Q3pLQkk/view?usp=sharing The usage is simple, you just take the printed template and place another page on it, you can see the guidelines through the page so you can use them to draw your mandala symmetrically.
So, my wife also tried using the template to make mandalas and I have to say her results were amazing. It was also the very first time she managed to get to the meditative state when drawing mandalas
Here are few testing mandalas plus also a reveal on how to draw these without rulers and compasses (for now it seems that the center is the weak spot, more tweaks will be needed)
Yesterday I figured a way to create a perfectly symmetric mandala without the need to use rulers, compasses, and stuff like that, purely by free hand. Today I tested it and it looks amazing. I will do some more tests and then I will send pictures and also a little how-to so you can start making amazing mandalas right away!
So today during the trip home I was drawing a random mandala to spend some spare time: Well, this is as good as a drawing in the bus can get I guess :D
