Depends on who you ask It takes about 2-4 days. 1 day to paint the eye, another day to set it in the setting and a third day to wrap the wire (sometimes I need to let it cure a little longer before wrapping)!
Those all sound cool. Flowers are always pretty and teeth/claws look cool on necklaces. As a matter of fact, I have one from vacation. There are infinite possibilities and I have no ideas as of yet, but I'm sure something will inspire you soon. Maybe it will be symbolic of something that you'll soon witness or experience. We'll see soon enough.
