Stencils are roughly 4"x4", although some may be slightly smaller or larger.
Images display samples of each of the patterns. Enameled sample image is just for an idea of what you can achieve with stencils, but is not specific to this exact set -- look closely and you'll notice the patterns in this set vary slightly from those used in the image, just to give a general idea for stencil use.
*** Stencils may have sharp edges from manufacture. Handle carefully! You'll want to sand these away upon receipt ***
