Snip the stem from the single gerbera daisy, leaving only 1 inch of protruding stem from the blossom.
Wrap the protruding stem with a 2-inch strip of florist tape. Use standard green to simply mimic the stem, or use a different color to accent your corsage creation.
Snip a length of ribbon from the roll measuring 12 to 24 inches depending on how long you want the bow to measure. Tie the length of ribbon into a simple bow. Squeeze a dab of craft glue onto the front of the knotted center of the bow.
Adhere the wrapped stem of the gerbera daisy to the glued part of the bow. Hold it in place for 10 seconds and release. Let it dry for 10 minutes.
Use the pushpin to attach the corsage to the front of your dress, or glue it to the top surface of an elastic wristband, which can be purchased at most craft and department stores.
