I’d like to know the process of customizing my own shoes with rhinestones, diamantes, crystals, etc myself. I don’t want to send them off anywhere as I’d like to be able to do them myself. Either a whole shoe or just the heel or just the strap. Can someone let me know what specific materials (glue, varnish, type of crystal, etc) I need and the actual process of applying them to the shoe securely? Thanks in advance!
