Always Plan. You may postpone your flower shopping until the last day before your wedding but it is always wise to plan ahead, as you may end up spending more than you expected doing the last_minute purchase. Moreover, planning ahead for your wedding flowers also gives you enough time to purchase the flowers that you want to have at your wedding rather than picking the available ones.
When I learned Ikebana as an adult, I was really fortunate to have had an old_fashioned sensei (instructor) who not only taught me the theory and techniques, but also immersed me in the respectable manners and ways of the good old days. It is through my sensei that I learned that Ikebana goes beyond the typical art form, and that it is more of a way of life; in fact, Ikebana is also known as kado, which literally means "the way of the flower."
