all it take is googly eyes (I’ve been OBSESSED this year with googly eyes! I actually hot glued these onto the nails –but they do have sticky back eye balls (head HERE)
The trick to hot gluing is to let it cool so it’s still tacky…but not hot. It’s around 10 seconds and you can test it by touching it to make sure it’s not hot and then press onto nail. If it doesn’t stick than you are waiting too long! Be careful so you don’t burn your nails!
