A decade into the marriage and still going strong? Nice. The official theme for the tenth anniversary is tin or aluminum. Gift ideas for this year that revolve around tin and aluminum? You can make it a funny one, by stacking up the fridge with cans of his or her favorite drink. On a more serious note, tin or aluminum photo frames, or a door sign that has your names carved on it or maybe even wind chimes.
Not all of us put in the time and effort when buying a gift, where those who actually do, are the best of the lot. It shows you care and love this person enough to put that much energy behind something that sounds simple, yet isn't.
