What's a good gift for our 6th year aniversary?

You can't go wrong with jewelry! Does she wear earrings? A bracelet or a necklace is also a good choice. Or if you want to go all out, a new ring? Hope this helps! Just stay away from applicances and keep it personal :)

Maybe 6 dozens of red roses or 6 different love cards or just make a game a hide 6 different gifts all over the house and then ask her to find them giving some romantic clues.

I have just looked up traditional gifts for 6th Anniversary. The answer was candy or iron. This could be chocolates or perhaps some sort of iron ornament. The modern gift for 6th anniversary is wood. Perhaps you could make something for your wife from wood - Jewellery box maybe. Hope this helps. I always like to give the appropriate gift. My sister celebrated her 1st anniversary this year which is paper. I got her and her husband cinema tickets. She loved it. Whatever you decide I hope you and your wife have a lovely day.
