Does anyone dry flowers?

I've dried flowers before but only in small quantities, usually just by hanging and air drying. My son and future daughter in law are getting married in Oct. of 2016 and are having a very country rustic theme to their wedding. I have two growing seasons to try to grow and dry as many flowers as I possibly can. (quả óc chó)
Their colors are yellow (sunflowers) and deep blues with white and green mixed in. If anyone has had any experiences with drying your flowers I would love to hear them. What were the best to dry, which retained color better, etc, etc...

 

I've never done it myself but the one I've heard of the most is Larkspur( annual Delphinium ).
Around here it's grown commercially, as it's what confetti is made of nowadays. You should be able to get some nice deep blues/purples from them.

 

A lot of the dark lavenders go dark blue when dried, but I doubt you have time to dry enough from new plants... Maybe look around friends' gardens, and beg some cut lavender flowers from those who have established plants?

 

Just thought I'd share this with you.......



A whole field full of Delphinium grown for drying.
