pants pockets or the in seam pockets. You can always add a sewn on pocket to anything you like. A sewn on pocket can be any shape that you can think of and any size. I am showing you the basics with a rectangle but you can really use your imagination when it comes to pockets. So to start you will cut out your pocket. And if you would like a flap to cover the top of your pocket you will want to cut out two of those. The pocket should be slightly larger than the flap pieces since you will fold under all the edges.
