You can give various shapes to your accessories by passing the fishing line through the beads.
An other idea is to make your jewellery with very thin wire, which is flexible and it can be bended to create different patterns like butterflies.
I have also tried rubber but I don’t recommend it as it is more difficult to create more complicated designs and it tends to loosen after a period of time.
You can even make necklaces without a clasp by filling strips of fishing line with beads which you join together.
