There are florists that are amazing flower designers and they don't have much previous experience _ they possess natural talents for creating beautiful designs and receive positive feedback on their design. There are others that require instruction and training before being able to create fabulous designs and receiving the good feedback. For those who fall into the latter case, the designer should seek out and take training classes as well as locating potential mentorship possibilities. Together these will help the person to enhance their skills and increase the amount of good reviews they receive. Also those in this latter category may do best, at least in the beginning, working in a designer position that follows recipes or formulas.
Next, fill your "real" vase about two_thirds of the way with warm water. Make sure it doesn't leak. Add flower food if available. (Follow the instructions on the packet.) Place a few of your larger blossom flowers in the vase and step back. This will give you a better idea of how to proportion your bouquet. If the stems are too long, simply cut them shorter. If they are too short, try a different container, or add pebbles or marbles to the bottom of the vase to elevate your flowers.
