For rings which are as cute as a button, start with ring blanks which you can source from online jewellery suppliers or craft stores.
Take your favourite buttons, beads, trinkets or scrabble letters and use a strong glue to secure them. I like to use Loctite Gel glue or similar which you can find from the hardware.
For a silver border around your button, glue down a metal washer first - again you can pick these up from the hardware and they come in various sizes.
Leave your completed rings over-night to set before wowing your friends with your glam creations.
