Floral Stem TapeFloral Stem tape is a strong stretchable tape that adheres to itself without sticking to your fingers. Available in a wide variety of colors, it is ideal for creating corsages, bouquets, headpieces, cascades, nosegays and boutonnières. As the tape is stretched, the adhesive material is activated as you wrap it around fresh, dried or silk flower stems. This tape is a must-have for making trendy flower crowns and paper flowers.
