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
E6000 adhesive
Toothpicks
Start by placing a dollop of E6000 glue onto a piece of cardboard or disposable surface. Use a toothpick to carefully apply a thin line of glue along a small section of the logo perimeter.
Turn all the crystals face up. Use a jewel setter or create your own tool by wrapping beeswax around the tip of a skewer or toothpick to pick up each crystal.
Apply the smaller crystals one by one along the perimeter. Add more glue as necessary.
Fill the logo area with the larger crystals. Utilize smaller crystals if needed to fill any remaining gaps or spaces.
Make sure to let it dry completely before repeating the steps. Use a damp cloth to wipe off any waxy residue left behind by the jewel setter.
Voilà! Your crystal-studded kicks are now completed and ready to shine.
