Just like what I said in the "Apps" chapter, I will teach you a way on how to find cutouts without cutting them out yourself. Well, it's easy. The answer is:
Just add the word "png" at the back of your character's name when you search for their pictures on the web. For example, Kristen Stewart png.
For more better cutouts, add one more word: deviantart. For example, Selena Gomez png deviantart.
Yes, just like what I said in the "Backgrounds" chapter, Deviantart is a great website where artists from all around the world gather! Not only backgrounds, the best pngs (cutouts) are also included.
