You can totally make these using jewelry wire - but I ran out, so I decided to use paperclips!
Bend & cut your paperclips
Pinch them together so it will fit into the coil end
Bend up a coil to attach to the hook earring.
This has to be done quickly:
Add a drop of glue inside the coil & end, & push in the paper clips
Add the hook earring & You're all done!
