Photo is too tiny, can you repost?
How are what made?
I think they are called neckerchief slides or woggles. What do you want to make one out of?
Souvenir From JK Convention in Korea 2014. Looks like a key chain ring with a piece or part of a bandana held with a concho. No instructions are available.
I'm unable to enlarge the picture. from William's description, I'd get a cheap key chain, a concho and a bandana, all from a craft store and play around with it until I got something similar.
sorry i was trying to help but it doesn't look like it will.
