When you have your fabric all sewn place your template on the fabric and move it around until you have a look you like. Then trace around the template.
Repeat this again for the second wing. What I forgot to do was to turn the template over so the second wing would be a mirror image of the first. If you give your wing a tail on one end you won't be able to put them together if you cut them out the same side. I realized what I had done and I sewed across the long tail I was going to use on one end so both ends on the one wing were reasonably the same.
