A tip for curved text - I draw the circle, then place H's around it where I want my text- the 'H' is wide and has a double-leg base, so it's easy to spin it to the arc, and get the correct angle. Then replace it with the letter you want, and it will have the rotation you need.
edit- and here's a yin yang symbol, with a breakdown of the parts in the order they're placed.
