You will need:
a pair of sneakers
300-400 Swarovski flatback 3.2mm round crystals
400-500 Swarovski flatback 4mm round crystals
jewel setter or skewer and beeswax
Flip all the crystals so they are all face up. Use the jewel setter, a wax tipped tool, to pick up each crystal. You can easily DIY your own jewel setter by balling up some beeswax on the tip of a skewer or toothpick.
Viola! Your crystal studded kicks are finished . . . bling bling.
