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.
If the flowers appear too bunched up, try cutting them at different lengths for more variety. Don't worry if some blooms don't stay in exactly the right position at first. Continue to the process by adding more flowers, adjusting their height and position as you go. The stems should all fit comfortably in the neck of the container and begin to hold their positions better as more flowers are added.
