Even within set it was different; Carly's hair went from straight to wavy. When Ava was at Charlie's Pub her hair was straightened to the left, and once at the Corinthos compound it was a bit more feathered to the right. Those kind of inconsistencies annoy me, lol.
I can't recall which magazine it was, but one featured a story in 1981 about Edge's 25th anniversary party. The story included a number of photos from the party and Karen Lynn Gorney was included. The article mentioned that Gorney was interested in assuming the role of Nicole.
