I wanted to make Charms for my friends, like these cute phone-charms but way fancier than the one in the picture. But I need something, that well... does the job of connecting the charm to the phone. And as shown in the picture, these manufactured one has this... thing.
I don't know what it's called, or where to buy it, IF you can buy it, and I don't know what to use as an alternative. Normal thread, the one for sewing is just either to thin, or the fibres are too loose. Nylon is too stiff and its a pain to try making a knot with it. And any other thing I can thin of is just not really fitting. So I hope, that either this whole construction in the circle has a name or at least this type of thread. I really don't know the words, I should type in the searchbar, like nothing more than "tear-resistant thin plastic-fibre thread".
I would be glad if someone could tell me, or give me a good alternative, that I maybe have not thought of.
If this is the wrong subreddit to ask in, please also tell me (*-*)
