Not that I believe in luck, but I saw this ceramic hand in a store and thought it looked like a good still-life subject. There was another hand that the fingers were in the shape of the peace sign.
There are a number of theories for the origins of this expression but the one that historians give most credit to is that the crossing of fingers started in the early days of Christianity when the religion was banned and followers were forced to develop secret signs to communicate with each other. One such sign is thought to have been the crossing of fingers by two people on meeting, who would identify themselves to each other by forming an L shape with their thumb and forefinger and then touching their thumbs together and crossing their index fingers to form a fish symbol (the ichthys, Greek for fish, being the ancient symbol of Christianity).
I love the different textures you've captured here
