Photos and Flowers
We had photos and handmade flowers at the three round tables and a long table. (We originally intended to use the long table to food but decided that the risk of food poisoning was too great.) The photos covered most of our guest list and a few people who couldn't make it, at various ages. We had 40 frames all together.
Originally I didn't want to have all three flower colors at one table. I thought it would look too July 4thish, but I didn't put the tables together and didn't micromanage. I'm glad I didn't, because it worked out well, I think.
