not sure if i am understanding but the last part about the theme, i think a date night or game night would be fun, But i definately wouldn't ask for recipies if you went with a date night theme, The only way i can get that to work in my mind and it is a huge stretch is if you only ask for desert recipies or horderves, ehh, it just doesn't make sense to me.
I like the idea of the Name sign, An idea i just did for a shower, was a personalized cake pan, There are a couple of sites on the internet, I think simply sublime was the company i used, They have lots of pretty designs and then you can have a personalization added, like Suzie's Kitchen or Fresh from the Kitchen of Lisa and Frank. I added boxed cake mix to the pan before i wrapped it. or you could add your fav recipies.
Have a great time!
