After giving these to a friend at school, through out the day, all she was asked was " Do you have pins in your ears? That's so unhygenic!" (She was asked this around fifteen times in a few hours).
Step 1: What You Will Need
Earring Posts and Backs- I use 4mm but 6mm would probably be better
Some Means of Cutting and Filing Down the Pointed Bit- I used a multi-tool, leatherman type thing.
Some Means of Sticking The Post to the Pin- I used a glue gun and hot glue
2 Coloured Push Pins- Green for me
