What does the vase opening stand for?
Vase opening stands for how big the opening is and how many stem flowers the vase can hold. There are no specific standards for the size of opening. It mostly depends on the favorite of the floral designer. Some of the designers like to put more greens in an arrangement. “Big mouth eats lots of flowers or greens”. But some of the designers will type the vase mouth to make it holds well with less flowers.
