Beautiful but difficult
I tried one of the stencils with stencil butter but the openings in the stencil are so fine that there were numerous places where the butter went under the stencil. This stencil must be used with a tacky glue to prevent that. I also tried the stencil with ink and had to push very hard with a finger dauber to get the ink through the narrow slits. The finished product was worth the effort.
