Mark the milestone with something you build together, not just something you buy. Our wooden flower bouquets never wilt, our music boxes play a tune once assembled, and our miniature houses light up on a shelf — different ways to make an anniversary feel like more than a card and a candle. Pick a piece that plays a song, blooms permanently on the counter, or captures a tiny scene the two of you actually recognize. Most kits take one relaxed sitting to finish, and they're built to last for years afterward — a gift that keeps marking the date long after the actual day is over.
