Think of stencils as a guide to putting painted images wherever you want. You can create murals on the wall, paint a piece of furniture, embellish a throw pillow, make art prints for framing, decorating a t-shirt or jeans, paint a rug or the floor. The possibilities are unlimited!
Stencils get an image in place that is sized right and has the correct symmetry. In other words, the face of the Lion above is the right size for his body. Sometimes that's hard to do just freehand and if you can't then a stencil puts you right where you want to be. Then you can embellish the painting however you want!
