Here's a little DIY wedding idea...
At many weddings not everyone can see what the couple are doing when they cut the cake. So I thought of the idea to put the mirror behind the cake to improve the view of the couple for the guests. Look past the couple you see the mirror** to the less obvious. I didn't realize, until looking at the photos, that you would be able see what the guests are doing. I love the looks on those kids faces - utter confusion and delight. And you can also see a little of the photographer. I like it. You might like to do something similar sometime and catch all the action going on.
**The mirror I picked up at a local Cameron antique shop for Christmas, for the daughter above. It was a great deal at $35. She painted the frame white, then used a robin's egg blue wash over it. It turned out beautiful.
