Learning how to preserve wedding flowers at home will save you money as having your flowers professionally dried will cost you hundreds, though you know they will do a great job.
Professionally freeze dried flowers cannot be duplicated at home and if you want your flowers to look almost as good as they did on the day then this really is the only way to go. This method is the only way that your flowers will hold their color and will take 3 to months to be completed. Make sure you ask to see examples of their work before you entrust them with your precious flowers! You will need to make sure that your flowers are collected by them as soon as possible - it would be a good idea to ask your wedding venue to keep the flowers in their chiller to preserve them as much as possible, not in a bucket of water. They will then dry your flowers and then either frame them or arrange them in a glass dome. The end result is beautiful but it will cost hundreds and after a few years you may not want your wedding flowers still displayed. Although I know some brides that 10 years later still do!
The alternative is to dry your flowers by yourself or ask a friend or family member as you will probably be a bit busy straight after the wedding - just think honeymoon!
I tried this with a beautiful bouquet of red roses. Their color was more brown than red but they have held their shape, they are very delicate so won't be as long lasting as pressing them but are much easier to display in a vase.
You could always preserve your flowers forever by choosing a silk bouquet and at least this way you could still toss your wedding bouquet for all your single female guests!
