what is the best shape of a parachute?

In my science class right now, we are making bottle rockets. I was wondering what the best shape of parachute to use is. Also, how should I attach the parachute to the rocket?

dome is better but almost impossible to steer

a dome for a water bottle rocket but a rectangular foil if you're flying (directing) the parachute and you want to steer it.
