I made several hair flowers for a friends birthday and I was trying to come up with something different. I kinda... Shabby Flower! This one is so easy it's ridiculous.
I started by cutting several 2 by 2 squares of fabric. The amount of squares will depend on how full you want the flower. After cutting the squares I cut with straight scissors in towards the middle BUT NOT ALL THE WAY! You don't want to cut the square into 4 complete triangles, but... almost.
Then take one square and pinch it in the middle. Use a needle and thread to hold that and just keep adding squares onto that!
