The stencils are made from reusable 190 micron mylar and will enable you to paint a whole room if you choose. Create a bespoke design to suit your needs - you can simply paint 1 tree in one colour or paint a whole forest of trees in different colours, it's up to you and how big you want your project to be. To create more complex designs you can paint lighter shade of trees as a back ground and then repeat over the top with darker tone to create a feeling of looking into a forest with background and foreground.
