To curve the ball from right to left use the inside of your foot, striking the bottom half of the right side of the ball.

Or if you want to curve the ball from left to right with your right foot, use the outside of your foot.

Aim to make contact with the bottom half of the left side of the ball.

In both cases your followthrough will not be in the direction of the target as you are cutting across the back of the ball rather than kicking through the centre of it.
