These are all the items you'll need. Everything except the cutting or exacto knife.
Take your crappy sneakers and clean them as much as you can. Yeah, i cleaned mine lol they're really old so there wasn't much i could for them.
Masking tape all the border of the sneaker you want to glitter. Even if we're really careful it can get messy.
Mix well in your cup the glitter and glue. I used the whole package of gold and like half of the pink one. Have fun and mix the colours you want to match or contrast the ones on your shoes.
Paint or glue or whatever your sneaker. Make sure that it's a thin layer because it's better to add a lot of thin layers rather one too thick that will probably never dry.
Wait for it to dry (make it faster by placing them near a heater). When it's COMPLETELY dried you can add the next layer. Use as much as you need to get the glitter effect you want.
After all your layers are dried help yourself with a knife to remove all the masking tape.
Peel carefully so that you don't remove anything more than the masking tape.
Do a little clean up (i didn't do a very good job lol).
