wedding gift ideas

I need some help. We are going to a wedding on Saturday (I am excited first wedding I have been to for 3 years) but I just wanted some input on what you have found you can't live without being married or not something for the household. I wanted to get creative but this tooth has ruined my creativeness over the last few weeks. My last resort is the registry. I am talking practical objects. Yes they are LDS so those things count too. So share your thoughts on stuff you just can't live without household wise.

I ask Daniel what he wants to get the couple and he says "I don't know" all the time.
