I have 1 knuckle tattoo. It’s a horseshoe. It’s on my middle finger, right hand. It goes with the theme of my sleeve, which is good luck/bad luck. I want to get the rest of my knuckles tattooed, using the horsesoe as a U, or just getting more good luck/bad luck symbols. One roommate says that it’s a bad idea, my other roommate says that as long as it goes with the style of tattoos that it’s a good idea. I know, it’s my tattoo and ultimately I have to make the choice, but I want to know more than these 2 people’s thoughts on the knuckle tattoos. Thanks in advance.
