DIY Photo Lantern. Print Black and white photos on vellum and tape them with doublesided tape on a lantern. (Or make a lantern of 3 or 4 photoframes) Combine photos and text. Think of all the things you can make one for: wedding, nursery, birth. Etc. etc.
What a cute idea for a friend's 40th (or 50th!) luncheon. I guess you have to laminate the photos and then put them inside the vase. I bet someone makes photo vases, but I'd hate to see how much they cost!
