Why is it hard to draw a perfect circle ?
I think it's just the human perception,we think it's a perfect circle but it isn't.That what the old compass is for,perfect circles.
Because our body shakes, we cant be completely still. Even drawing a decent circle is hard :P
It takes mad skills for that.(french accent)
You can use a protractor or compass as I did long ago in high school to draw a perfect circle. Or you can place a cup or glass on a piece of paper and trace it, creating a "perfect" circle The other members are correct, stars all around! = )
Because we are just humans who can't even be still and draw a perfect circle....
My friend told me that if you can draw a perfect circle then you're probably be a demon. So, don't feel bad about not being able to draw one; it just means you're human. :)
