- A keyring with a chain (mine were saved from old keyrings but you can buy them like that)
- Jump rings (mine are 7mm)
- Small buttons (you need ones where the gap between the hole and the edge is smaller than your jump rings)
- 2 x pliers
pop it through one of the button holes
and one chain on the keyring.
Then just close it up.
Easy, then do it again with another button.
Just add as many buttons as you like in whatever colours and combinations you like.
