How to make straight hair wavy?

My hairs naturally straight, and to get it wavey i plait it or twist it when its damp them i take it out in the morning, you could spray it with hairspray to keep it in place but you dont really need to, also if you plait it then make sure you do it about a quarter of the way down otherwise it looks a little bushy or just to scrunch it put it in loose plaits take them out then scrunch it upwards with your hand covered in moose, good luck :)
