Scratch Interface - Costume Pane
The costume pane is where you can load the costumes for your sprite. You would use costumes to animate or change the appearance of the sprite in your game or story. You can create a new costume with the built-in paint utility, import an existing costume, or use your computer's camera to take a picture and use it as a costume. On the costume list, you can copy, edit, rename, and delete the costumes. You can also reorder the costumes by dragging them into your desired order.
