OO, OO, another idea then... I gave my godparents (for christmas, but still a neat idea) A bottle of flavored olive oil and a shaker of italian seasoning mixes and a set of 4 little dishes for bread dipping. They loved it. It's a fun thing to nibble on while making dinner (unless they prefer to nibble on each other, per your hubby's research...
I have also given as wedding gift a nice bottle of champagne a dinner gift certificate so they perhaps have an option to use for a "first anniversary" celebration.
Or how's about some bucks toward golfing time or lessons to brush up their skills. Or a couples spa day? or or or... a cooking class?
gads, why don't we get this kind of stuff?
