I went to buy some basic rings from a crafts'store. They would've cost way too much. Only two simple rings were 4,5 euros! So, I had a plan B. I bought some really strong metal yarn (or sticks, you could say). I bought also some soft foam that could be used with the sword. Any way, I bought the metal sticks, went home, ate something and started with the rings. I couldn't believe myself doing the rings this way too... But apparently, it works. I use this white modelling clay with almost everything. Anything. Except with clothes.
When the rings are ready, I'll add some photos of them. I've realised that they are actually very important for Jack. You know how he swings his fingers smoothly? It wouldn't look really anything without the rings once he got them. 'Got them' is the right expression. You know the golden simple ring around his left forefinger? He got it from Tia Dalma. Stole it, really.
