1
Steal a pair of shoes from a Barbie when she's not looking. Alternatively, you could just buy a pack of doll shoes from your local toy shop.
2
Hold the shoe in place and carefully drill a hole through the heel of the shoe. If you don't have a drill at hand, you can hammer a nail through the shoe instead - but be careful, it's quite tricky.
3
Open a jump ring with some jewellery pliers and slip through the hole on the shoe.
4
Slip an earring hook on to the jump ring and close the jump ring.
5
Repeat with the other shoe and you've made yourself a cute pair of earrings.
