A friend of ours recently mentioned that years ago when she and her hubby had very little money they agreed to exchange love letters on Christmas day. This has become a tradition that they both enjoy and look forward to a great deal.
Seems to me this is a very good tradition, regardless of what other gifts you do or do not give. May I suggest you either this tradition this year by writing a love letter for your bride? Or, discuss it now so your wife can write one for you.
If you do this, please put a good deal of time and thought into it. This is a chance to really bless her in a deep and meaningful way.
