Cindi-
I've always liked to tuck dried blooms here and there, and they are especially nice in the fall/winter when fresh blooms aren't available, IMHO. In one of our many moves, I trashed all of my dried blooms thinking that I'd just dry more, but my hydrangea days have been over ever since
I saw a pin the other day on for a beautiful bloom wreath, and said "That's it! I MUST have more at once!"
I miss them!
I've dried them using a vase of water- just fill the vase up a little bit (an inch or so) and let the blooms draw up the water. Just leave them, and they will dry on their own. When I did them that way, I never got the color to stay, but they still are very fun brown.
Same way, but add glycerine, and you can get more color to stay in the bloom.
