You will very likely have to seek additional advanced training. We believe that when you go to a floral school you should have the confidence that the program is set up to give you a thorough practical training. All of our courses include vase arrangements, wedding designs, sympathy flowers, flowers to wear, and novelties. To really learn floral designing you have to do it. This doesn't mean that every design that you will be taught will be big or contain overwhelming amounts of flowers.
Some designs are bigger and some smaller.
Some flowers fancier, and some more common, but your course should provide you with flowers to use at each session. Be careful about any course or program that requires you to bring your own flowers, or that is vague about flower costs, and requires you to buy them separately at the time of class. The overall cost of that program could end up being significantly higher than you may have planned on. In other words, Your time is valuable. You should be making floral designs, not wasting time by taking apart floral projects that you have already made, to recycle the flowers over and over again.
