as long as you're fairly competant with a glue gun, this is a cinch... make sure you get a button big enough to cover the top of the key, which should ideally be long and of the skeleton variety. I used a glossy acrylic paint because trial runs with matte made it rough to the touch, and it bothered me. glue the button to the key, paint it, let it dry, then string it and you're ready to explore the Other world.
