I will do a more indepth tutorial for hair in the future but Ive been asked about this man here and how I did his bangs. This one's actually one I made in 5 seconds with a scrap piece as a magnetic extra. And it's actually one flat piece with both sides brushed on the backing. Using this brush or somthing like it.
All you do is cut the shape of bangs you want and brush the backing using that brush!
