I used gold card stock and folded it in half. On the fold is where I drew the curve of the ear while using the bottom edge of the paper for the flat opening for the real ear. I sketched out the pointy ear shape in pencil. Then I cut out the shape I wanted. Once it was cut out I used scotch tape to connect the front and the back leaving the flat bottom opened.
My first one didn't fit right so I had to make two sets. Good luck!!!! Happy elfing !
