Vampire Mermaid Cookie for Halloween

Over the summer my friend Marlyn of Montreal Confections got me into cutting my own stencils with a Silhouette Portrait. I created a mermaid scales stencil for this mermaid tail cookie and it got me thinking about how I could use the same stencil for more than one design. I got a little creative and came up with this vampire mermaid cookie!
