Shortening corsage pins is necessary to use as accessories in the center of flowers or on boutonniere stems. Be sure to don protective safety glasses to protect your eyes in case a sharp metal point goes flying.
Don't feel limited to white. Corsage pearl pins come in a lot of different colors to match different wedding schemes.
After putting on your safety glasses, bury the pin into a stiff block of dry florist foam and snip with a heavy pair of wire cutters. Place your finger on top of the pearl so it doesn't go flying.
The pin should be short enough that it doesn't go through the other side of the boutonniere. Push the pin in at an upward slant.
