Cut a piece of leather approx. 45cm in length. Fold one end over to make a loop big enough to fit around the large ring and use the rivet tool to make a hole through the leather where it overlaps (you will use this to secure the loop).

You may need to make the hole larger to fit the rivet through. Push the rivet through both holes and press on the back, adding a dab of glue to ensure a secure finish. Repeat this process on the other side of the leather.

Now open the large ring. Clip it through one of the loops you have created in the leather, then take the other end of leather through the centre of the large ring and bring it back round to clip on to the other side of the large ring.
