I kind of made these on a whim in my spare time a few weeks ago. I had two pendant blanks, so I flipped them upside down, cut apart the Queen of Spades and Hearts from an incomplete deck of Bicycle cards and placed them in there.. then I hung some dice from the part where they were supposed to hang from a necklace. Then I added some backings, turning these into brooches.
