I’ve knitted two socks and the selfstriping purple glitter yarn striped exactly the same!
The first sock had a blue toe, the second sock got a purple glitter yarn toe and still they striped exactly the same:

And it’s family too:
I didn’t plan for any of this, it’s all coincidence. The yarn must really like me. The feeling is mutual. (glitter!)
