Although I'm looking at brighter and bolder blues, I like the look of the tiffany blue example. I love how the ribbon band around the centerpiece ties into a matching ribbon on the favor boxes, and I love the stick on gem on the favors as well. I also like how these pictures show that coordinating PAPER plates can look gorgeous and not at all tacky. Especially for anyone, like us, who is planning to take care of the wedding sans caterer, and doesn't want to have to rent a ton of china. And note the giant "diamond" ring at the base of the centerpiece. I've seen those advertised as paper weights. They would be great when used as part of the decor, and then (cleaned up if needed) and given to bridesmaids, mothers, and other VIPs of your wedding as gifts.
The car decal is soooo cute. It is just a static cling sticker, cut precisely around the lettering giving it a painted on look that is non permanent and will not ruin the finish of the car.
The silver flutes are stunning, but the labelless wine bottle with the hand painted initial on it is the part that steals the show. I know the torches in the second picture are not blue, but they came from the same wedding on the beach as the first set of pictures and I just had to include them here.
