Custom Shapes came along beginning with version 6 of Photoshop. With Custom Shapes, you can do much more with vector graphics than you could before. Custom Shapes are really useful; if you have created a difficult shape once it is better to save it as custom shape so you can use it in your further design projects. Once you have made a path into a Custom Shape, you can, with a click-drag of the mouse, create a new copy of that shape, in any size, color, or layer style you want, anytime and anywhere. So it is very easy to use. I really hope you find this list useful!
