These metal settings are perfect to use when glue is not appropriate. Look great on Leather and suede. These settings are placed on the RIGHT side of the fabric. Place the rhinestone on the right side of the fabric with the shiny side up. Next, place the setting with the prongs pushing through the fabric from the right side to the wrong side, securing the rhinestone to the fabric. Gently push the prongs towards the center of the setting on the wrong side of the fabric.
