How to draw a 3D letter O?

I’m making a pamphlet for my class and i want it to be very decorative so i thought to just print out 3d letters. Turns out my printers out of ink so i have to hand draw it. The title of it is: How to connect to wifi on Mario Kart DS. a lil’ long but still. i’m only having trouble with o since its all circular and all.
