1. First you need a button with a bit of a well in it.
Here I'm using a Stampin' Up! button. Apply a glue dot to the well.
over the glue dot onto the button.
2. Once I have it on the button I press the glue dot into place from the back side.3. Next I dip the button upside down into glitter
(here I'm using Stampin' Up! Dazzling Diamonds).
