Red string tattoo on hand: Here’s what it means
One that I’ve seen a good many times over the years – and, until now, never thought to research, I might add – is that of the so-called ‘red string of fate’.

As I said, I’d seen the tattoo on a number of people. Enough, certainly, to notice a pattern. This mark had to mean something, I just had no idea what.
So I did a little digging – thanks, internet – and found that the red string tattoo in question is known in Asian cultures as the ‘red string of fate’. Most commonly appearing on the thumb of a man and the pinky finger of a woman, the tattoo looks like a simple bow with tails, not unlike a tied shoelace.
