These are some copper earring hooks that I made out of wire during a demo at college (I also learned how to make the jump rings you can see attached to the hooks) I’ve been meaning to post about this for a while as I was surprised at how easy it was to do.
All you need is some pre-softened wire, I think we used about a 0.8 guage which means it will be strong enough to hold its shape while still fitting through the piercing. So cut a length of wire depending on how long you want the hook. Use a needle file to smooth and flatten one end of the wire. Take some round nose pliers and working on the end you just filed, curl it up until you have a small closed circle. This is where the jump rings are hanging from in my picture.
Decide where you want the hook to hang in the ear and using the pliers and you fingers, make quite an open bend so that the two ends of the wire now sit parallel to each other. If this back piece is too long, snip off some wire with wire cutters. Using the file again, flatten and smooth the end, making sure not to file into a spike as this would cut the wearer when they try to put the earrings in. Next use some flat nose pliers to make a small kink in the end, this looks good and can also help to stop the earring falling out.
Lastly take a small hammer, and very gently hammer the curve and circle of the earring hook. This pushes the particles of the wire together and makes the wire harder so that it keeps its shape. This could also be done using a metal burring tool and rubbing over the areas you want stronger.
I asked if you needed to sterilise the earring hooks when they were finished and apparently just wiping over them with alcohol gel would work. So it’s that easy! I think for small projects it would be easier to buy hooks as they can be very cheap, but for pieces that have taken a long time to make, hanging them on hand-made findings would look more suitable (plus you could charge more if you were selling them!)
