I made this for my steampunk Queen of Hearts costume, but was really inspired by the kids' movie Robots. Madame Gasket, voiced by Jim Broadbent (love!), is such a nasty, gritty, gravely antagonist. The dark side of my heart loves her.
A brief how-to:
Glue the button to the ring blank, centering the button holes on the blank's disc. (In my case the "disc" was square. It all works.) Let it dry.
Glue the pointy, curvy, evil-looking watch bits and the focal to the button. On my ring I centered the focal, which is open in the center, and flanked it on either side with watch bits. Flat curved bead drops would look good here, too. Let this step dry
Glue the larger watch bit over the bases of the pointy bits. I could see substituting a cabochon for the watch bit here, but that would sort of remove the steampunky flavor, donchathink?
Let it dry overnight, and test your connections to make sure it's sturdy. If so, slip it on your finger and threaten the general populace.
