Here is the zip file for the elf ears. To attach it here I had to give the file a ".TXT" file extension. Save the file as "ElfEarsA.zip" that is to say loose the ".TXT" part of the file extension. If you can't see the ".TXT" extension open Windows Explorer, from the Tools menu select Folder Options, then in the View tab, remove the check mark next to "Hide file extensions of known file types.

Extract the zip to your main Poser folder. More details are in the zip file in the "Elf Ears A.txt". The file to apply the morph will be placed in the path:
